+# Battery Emulator Webserver
+This webserver creates a WiFi access point. It also connects ot an existing network.
+The webserver intends to display useful information to the user of the battery emulator
+development board, without the need to physically connect to the board via USB.
+The webserver implementation also provides the option to update the firmware of the board over the air.
+
+To use the webserver, follow the following steps:
+- Connect to the board via Serial, and boot up the board.
+- The IP address of the WiFi access point is printed to Serial when the board boots up. Note this down.
+- Connect to the access point created by board via a WiFi-capable device
+- On that device, open a webbrowser and type the IP address of the WiFi access point.
+- If the ssid and password of an existing WiFi network are provided, the board will also connect to this network. The IP address obtained on the existing network is shown in the webserver. Note this down.
+- From this point onwards, any device connected to the existing WiFi network can access the webserver via a webbrowser. To do this:
+ - Connect your WiFi-capable device to the existing nwetork.
+ - Open a webbrowser and type the IP address obtained on the existing WiFi network.
+
+To update the software over the air:
+- In Arduino, go to `Sketch` > `Export Compiled Binary`. This will create the `.bin` file that you need to update the firmware. It is found in the folder `Software/build/`
+- In your webbrowser, go to the url consisting of the IP address, followed by `/update`, for instance `http://192.168.0.224/update`.
+- In the webbrowser, follow the steps to select the `.bin` file and to upload the file to the board.
+
+## Future work
+This section lists a number of features that can be implemented as part of the webserver in the future.
+
+- TODO: display state of charge
+- TODO: display battery hardware selected
+- TODO: display emulated inverter communication protocol selected
+- TODO: list all available ssids: scan WiFi Networks https://randomnerdtutorials.com/esp32-useful-wi-fi-functions-arduino/
+- TODO: add option to add/change ssid and password and save, connect to the new ssid (Option: save ssid and password using Preferences.h library https://randomnerdtutorials.com/esp32-save-data-permanently-preferences/)
+- TODO: display WiFi connection strength (https://randomnerdtutorials.com/esp32-useful-wi-fi-functions-arduino/)
+- TODO: display CAN state (indicate if there is a communication error)
+- TODO: display battery errors in battery diagnosis tab
+- TODO: display inverter errors in battery diagnosis tab
+- TODO: add functionality to turn WiFi AP off
+- TODO: fix IP address on home network (https://randomnerdtutorials.com/esp32-static-fixed-ip-address-arduino-ide/)
+- TODO: set hostname (https://randomnerdtutorials.com/esp32-set-custom-hostname-arduino/)
+
+# References
+The code for this webserver is based on code provided by Rui Santos at https://randomnerdtutorials.com.

+ GNU AFFERO GENERAL PUBLIC LICENSE
+ Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+ A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate. Many developers of free software are heartened and
+encouraged by the resulting cooperation. However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+ The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community. It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server. Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+ An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals. This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU Affero General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Remote Network Interaction; Use with the GNU General Public License.
+
+ Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software. This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time. Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+
+ Copyright (C)
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU Affero General Public License as published
+ by the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU Affero General Public License for more details.
+
+ You should have received a copy of the GNU Affero General Public License
+ along with this program. If not, see .
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source. For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code. There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+.

+
+ This example provides with a bare minimal app with ElegantOTA functionality.
+
+ Github: https://github.com/ayushsharma82/ElegantOTA
+ WiKi: https://docs.elegantota.pro
+
+ Works with following hardware:
+ - ESP8266
+ - ESP32
+ - RP2040 (with WiFi) (Example: Raspberry Pi Pico W)
+
+
+ Important note for RP2040 users:
+ - RP2040 requires LittleFS partition for the OTA updates to work. Without LittleFS partition, OTA updates will fail.
+ Make sure to select Tools > Flash Size > "2MB (Sketch 1MB, FS 1MB)" option.
+ - If using bare RP2040, it requires WiFi module like Pico W for ElegantOTA to work.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+### Async TCP Library for ESP32 Arduino
+
+[](https://gitter.im/me-no-dev/ESPAsyncWebServer?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+This is a fully asynchronous TCP library, aimed at enabling trouble-free, multi-connection network environment for Espressif's ESP32 MCUs.
+
+This library is the base for [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer)
+
+## AsyncClient and AsyncServer
+The base classes on which everything else is built. They expose all possible scenarios, but are really raw and require more skills to use.

+## Installation
+
+### Using PlatformIO
+
+[PlatformIO](http://platformio.org) is an open source ecosystem for IoT development with cross platform build system, library manager and full support for Espressif ESP8266/ESP32 development. It works on the popular host OS: Mac OS X, Windows, Linux 32/64, Linux ARM (like Raspberry Pi, BeagleBone, CubieBoard).
+
+1. Install [PlatformIO IDE](http://platformio.org/platformio-ide)
+2. Create new project using "PlatformIO Home > New Project"
+3. Update dev/platform to staging version:
+ - [Instruction for Espressif 8266](http://docs.platformio.org/en/latest/platforms/espressif8266.html#using-arduino-framework-with-staging-version)
+ - [Instruction for Espressif 32](http://docs.platformio.org/en/latest/platforms/espressif32.html#using-arduino-framework-with-staging-version)
+ 4. Add "ESP Async WebServer" to project using [Project Configuration File `platformio.ini`](http://docs.platformio.org/page/projectconf.html) and [lib_deps](http://docs.platformio.org/page/projectconf/section_env_library.html#lib-deps) option:
+
+```ini
+[env:myboard]
+platform = espressif...
+board = ...
+framework = arduino
+
+# using the latest stable version
+lib_deps = ESP Async WebServer
+
+# or using GIT Url (the latest development version)
+lib_deps = https://github.com/me-no-dev/ESPAsyncWebServer.git
+```
+ 5. Happy coding with PlatformIO!
+
+## Why should you care
+- Using asynchronous network means that you can handle more than one connection at the same time
+- You are called once the request is ready and parsed
+- When you send the response, you are immediately ready to handle other connections
+ while the server is taking care of sending the response in the background
+- Speed is OMG
+- Easy to use API, HTTP Basic and Digest MD5 Authentication (default), ChunkedResponse
+- Easily extendible to handle any type of content
+- Supports Continue 100
+- Async WebSocket plugin offering different locations without extra servers or ports
+- Async EventSource (Server-Sent Events) plugin to send events to the browser
+- URL Rewrite plugin for conditional and permanent url rewrites
+- ServeStatic plugin that supports cache, Last-Modified, default index and more
+- Simple template processing engine to handle templates
+
+## Important things to remember
+- This is fully asynchronous server and as such does not run on the loop thread.
+- You can not use yield or delay or any function that uses them inside the callbacks
+- The server is smart enough to know when to close the connection and free resources
+- You can not send more than one response to a single request
+
+## Principles of operation
+
+### The Async Web server
+- Listens for connections
+- Wraps the new clients into ```Request```
+- Keeps track of clients and cleans memory
+- Manages ```Rewrites``` and apply them on the request url
+- Manages ```Handlers``` and attaches them to Requests
+
+### Request Life Cycle
+- TCP connection is received by the server
+- The connection is wrapped inside ```Request``` object
+- When the request head is received (type, url, get params, http version and host),
+ the server goes through all ```Rewrites``` (in the order they were added) to rewrite the url and inject query parameters,
+ next, it goes through all attached ```Handlers```(in the order they were added) trying to find one
+ that ```canHandle``` the given request. If none are found, the default(catch-all) handler is attached.
+- The rest of the request is received, calling the ```handleUpload``` or ```handleBody``` methods of the ```Handler``` if they are needed (POST+File/Body)
+- When the whole request is parsed, the result is given to the ```handleRequest``` method of the ```Handler``` and is ready to be responded to
+- In the ```handleRequest``` method, to the ```Request``` is attached a ```Response``` object (see below) that will serve the response data back to the client
+- When the ```Response``` is sent, the client is closed and freed from the memory
+
+### Rewrites and how do they work
+- The ```Rewrites``` are used to rewrite the request url and/or inject get parameters for a specific request url path.
+- All ```Rewrites``` are evaluated on the request in the order they have been added to the server.
+- The ```Rewrite``` will change the request url only if the request url (excluding get parameters) is fully match
+ the rewrite url, and when the optional ```Filter``` callback return true.
+- Setting a ```Filter``` to the ```Rewrite``` enables to control when to apply the rewrite, decision can be based on
+ request url, http version, request host/port/target host, get parameters or the request client's localIP or remoteIP.
+- Two filter callbacks are provided: ```ON_AP_FILTER``` to execute the rewrite when request is made to the AP interface,
+ ```ON_STA_FILTER``` to execute the rewrite when request is made to the STA interface.
+- The ```Rewrite``` can specify a target url with optional get parameters, e.g. ```/to-url?with=params```
+
+### Handlers and how do they work
+- The ```Handlers``` are used for executing specific actions to particular requests
+- One ```Handler``` instance can be attached to any request and lives together with the server
+- Setting a ```Filter``` to the ```Handler``` enables to control when to apply the handler, decision can be based on
+ request url, http version, request host/port/target host, get parameters or the request client's localIP or remoteIP.
+- Two filter callbacks are provided: ```ON_AP_FILTER``` to execute the rewrite when request is made to the AP interface,
+ ```ON_STA_FILTER``` to execute the rewrite when request is made to the STA interface.
+- The ```canHandle``` method is used for handler specific control on whether the requests can be handled
+ and for declaring any interesting headers that the ```Request``` should parse. Decision can be based on request
+ method, request url, http version, request host/port/target host and get parameters
+- Once a ```Handler``` is attached to given ```Request``` (```canHandle``` returned true)
+ that ```Handler``` takes care to receive any file/data upload and attach a ```Response```
+ once the ```Request``` has been fully parsed
+- ```Handlers``` are evaluated in the order they are attached to the server. The ```canHandle``` is called only
+ if the ```Filter``` that was set to the ```Handler``` return true.
+- The first ```Handler``` that can handle the request is selected, not further ```Filter``` and ```canHandle``` are called.
+
+### Responses and how do they work
+- The ```Response``` objects are used to send the response data back to the client
+- The ```Response``` object lives with the ```Request``` and is freed on end or disconnect
+- Different techniques are used depending on the response type to send the data in packets
+ returning back almost immediately and sending the next packet when this one is received.
+ Any time in between is spent to run the user loop and handle other network packets
+- Responding asynchronously is probably the most difficult thing for most to understand
+- Many different options exist for the user to make responding a background task
+
+### Template processing
+- ESPAsyncWebserver contains simple template processing engine.
+- Template processing can be added to most response types.
+- Currently it supports only replacing template placeholders with actual values. No conditional processing, cycles, etc.
+- Placeholders are delimited with ```%``` symbols. Like this: ```%TEMPLATE_PLACEHOLDER%```.
+- It works by extracting placeholder name from response text and passing it to user provided function which should return actual value to be used instead of placeholder.
+- Since it's user provided function, it is possible for library users to implement conditional processing and cycles themselves.
+- Since it's impossible to know the actual response size after template processing step in advance (and, therefore, to include it in response headers), the response becomes [chunked](#chunked-response).
+

+
+### ArduinoJson Basic Response
+This way of sending Json is great for when the result is below 4KB
+```cpp
+#include "AsyncJson.h"
+#include "ArduinoJson.h"
+
+
+AsyncResponseStream *response = request->beginResponseStream("application/json");
+DynamicJsonBuffer jsonBuffer;
+JsonObject &root = jsonBuffer.createObject();
+root["heap"] = ESP.getFreeHeap();
+root["ssid"] = WiFi.SSID();
+root.printTo(*response);
+request->send(response);
+```
+
+### ArduinoJson Advanced Response
+This response can handle really large Json objects (tested to 40KB)
+There isn't any noticeable speed decrease for small results with the method above
+Since ArduinoJson does not allow reading parts of the string, the whole Json has to
+be passed every time a chunks needs to be sent, which shows speed decrease proportional
+to the resulting json packets
+```cpp
+#include "AsyncJson.h"
+#include "ArduinoJson.h"
+
+
+AsyncJsonResponse * response = new AsyncJsonResponse();
+response->addHeader("Server","ESP Async Web Server");
+JsonObject& root = response->getRoot();
+root["heap"] = ESP.getFreeHeap();
+root["ssid"] = WiFi.SSID();
+response->setLength();
+request->send(response);
+```
+
+## Serving static files
+In addition to serving files from SPIFFS as described above, the server provide a dedicated handler that optimize the
+performance of serving files from SPIFFS - ```AsyncStaticWebHandler```. Use ```server.serveStatic()``` function to
+initialize and add a new instance of ```AsyncStaticWebHandler``` to the server.
+The Handler will not handle the request if the file does not exists, e.g. the server will continue to look for another
+handler that can handle the request.
+Notice that you can chain setter functions to setup the handler, or keep a pointer to change it at a later time.
+
+### Serving specific file by name
+```cpp
+// Serve the file "/www/page.htm" when request url is "/page.htm"
+server.serveStatic("/page.htm", SPIFFS, "/www/page.htm");
+```
+
+### Serving files in directory
+To serve files in a directory, the path to the files should specify a directory in SPIFFS and ends with "/".
+```cpp
+// Serve files in directory "/www/" when request url starts with "/"
+// Request to the root or none existing files will try to server the defualt
+// file name "index.htm" if exists
+server.serveStatic("/", SPIFFS, "/www/");
+
+// Server with different default file
+server.serveStatic("/", SPIFFS, "/www/").setDefaultFile("default.html");
+```
+
+### Serving static files with authentication
+
+```cpp
+server
+ .serveStatic("/", SPIFFS, "/www/")
+ .setDefaultFile("default.html")
+ .setAuthentication("user", "pass");
+```
+
+### Specifying Cache-Control header
+It is possible to specify Cache-Control header value to reduce the number of calls to the server once the client loaded
+the files. For more information on Cache-Control values see [Cache-Control](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9)
+```cpp
+// Cache responses for 10 minutes (600 seconds)
+server.serveStatic("/", SPIFFS, "/www/").setCacheControl("max-age=600");
+
+//*** Change Cache-Control after server setup ***
+
+// During setup - keep a pointer to the handler
+AsyncStaticWebHandler* handler = &server.serveStatic("/", SPIFFS, "/www/").setCacheControl("max-age=600");
+
+// At a later event - change Cache-Control
+handler->setCacheControl("max-age=30");
+```
+
+### Specifying Date-Modified header
+It is possible to specify Date-Modified header to enable the server to return Not-Modified (304) response for requests
+with "If-Modified-Since" header with the same value, instead of responding with the actual file content.
+```cpp
+// Update the date modified string every time files are updated
+server.serveStatic("/", SPIFFS, "/www/").setLastModified("Mon, 20 Jun 2016 14:00:00 GMT");
+
+//*** Chage last modified value at a later stage ***
+
+// During setup - read last modified value from config or EEPROM
+String date_modified = loadDateModified();
+AsyncStaticWebHandler* handler = &server.serveStatic("/", SPIFFS, "/www/");
+handler->setLastModified(date_modified);
+
+// At a later event when files are updated
+String date_modified = getNewDateModfied();
+saveDateModified(date_modified); // Save for next reset
+handler->setLastModified(date_modified);
+```
+
+### Specifying Template Processor callback
+It is possible to specify template processor for static files. For information on template processor see
+[Respond with content coming from a File containing templates](#respond-with-content-coming-from-a-file-containing-templates).
+```cpp
+String processor(const String& var)
+{
+ if(var == "HELLO_FROM_TEMPLATE")
+ return F("Hello world!");
+ return String();
+}
+
+// ...
+
+server.serveStatic("/", SPIFFS, "/www/").setTemplateProcessor(processor);
+```
+
+## Param Rewrite With Matching
+It is possible to rewrite the request url with parameter matchg. Here is an example with one parameter:
+Rewrite for example "/radio/{frequence}" -> "/radio?f={frequence}"
+
+```cpp
+class OneParamRewrite : public AsyncWebRewrite
+{
+ protected:
+ String _urlPrefix;
+ int _paramIndex;
+ String _paramsBackup;
+
+ public:
+ OneParamRewrite(const char* from, const char* to)
+ : AsyncWebRewrite(from, to) {
+
+ _paramIndex = _from.indexOf('{');
+
+ if( _paramIndex >=0 && _from.endsWith("}")) {
+ _urlPrefix = _from.substring(0, _paramIndex);
+ int index = _params.indexOf('{');
+ if(index >= 0) {
+ _params = _params.substring(0, index);
+ }
+ } else {
+ _urlPrefix = _from;
+ }
+ _paramsBackup = _params;
+ }
+
+ bool match(AsyncWebServerRequest *request) override {
+ if(request->url().startsWith(_urlPrefix)) {
+ if(_paramIndex >= 0) {
+ _params = _paramsBackup + request->url().substring(_paramIndex);
+ } else {
+ _params = _paramsBackup;
+ }
+ return true;
+
+ } else {
+ return false;
+ }
+ }
+};
+```
+
+Usage:
+
+```cpp
+ server.addRewrite( new OneParamRewrite("/radio/{frequence}", "/radio?f={frequence}") );
+```
+
+## Using filters
+Filters can be set to `Rewrite` or `Handler` in order to control when to apply the rewrite and consider the handler.
+A filter is a callback function that evaluates the request and return a boolean `true` to include the item
+or `false` to exclude it.
+Two filter callback are provided for convince:
+* `ON_STA_FILTER` - return true when requests are made to the STA (station mode) interface.
+* `ON_AP_FILTER` - return true when requests are made to the AP (access point) interface.
+
+### Serve different site files in AP mode
+```cpp
+server.serveStatic("/", SPIFFS, "/www/").setFilter(ON_STA_FILTER);
+server.serveStatic("/", SPIFFS, "/ap/").setFilter(ON_AP_FILTER);
+```
+
+### Rewrite to different index on AP
+```cpp
+// Serve the file "/www/index-ap.htm" in AP, and the file "/www/index.htm" on STA
+server.rewrite("/", "index.htm");
+server.rewrite("/index.htm", "index-ap.htm").setFilter(ON_AP_FILTER);
+server.serveStatic("/", SPIFFS, "/www/");
+```
+
+### Serving different hosts
+```cpp
+// Filter callback using request host
+bool filterOnHost1(AsyncWebServerRequest *request) { return request->host() == "host1"; }
+
+// Server setup: server files in "/host1/" to requests for "host1", and files in "/www/" otherwise.
+server.serveStatic("/", SPIFFS, "/host1/").setFilter(filterOnHost1);
+server.serveStatic("/", SPIFFS, "/www/");
+```
+
+### Determine interface inside callbacks
+```cpp
+ String RedirectUrl = "http://";
+ if (ON_STA_FILTER(request)) {
+ RedirectUrl += WiFi.localIP().toString();
+ } else {
+ RedirectUrl += WiFi.softAPIP().toString();
+ }
+ RedirectUrl += "/index.htm";
+ request->redirect(RedirectUrl);
+```
+
+## Bad Responses
+Some responses are implemented, but you should not use them, because they do not conform to HTTP.
+The following example will lead to unclean close of the connection and more time wasted
+than providing the length of the content
+
+### Respond with content using a callback without content length to HTTP/1.0 clients
+```cpp
+//This is used as fallback for chunked responses to HTTP/1.0 Clients
+request->send("text/plain", 0, [](uint8_t *buffer, size_t maxLen, size_t index) -> size_t {
+ //Write up to "maxLen" bytes into "buffer" and return the amount written.
+ //You will be asked for more data until 0 is returned
+ //Keep in mind that you can not delay or yield waiting for more data!
+ return mySource.read(buffer, maxLen);
+});
+```
+
+## Async WebSocket Plugin
+The server includes a web socket plugin which lets you define different WebSocket locations to connect to
+without starting another listening service or using different port
+
+### Async WebSocket Event
+```cpp
+
+void onEvent(AsyncWebSocket * server, AsyncWebSocketClient * client, AwsEventType type, void * arg, uint8_t *data, size_t len){
+ if(type == WS_EVT_CONNECT){
+ //client connected
+ os_printf("ws[%s][%u] connect\n", server->url(), client->id());
+ client->printf("Hello Client %u :)", client->id());
+ client->ping();
+ } else if(type == WS_EVT_DISCONNECT){
+ //client disconnected
+ os_printf("ws[%s][%u] disconnect: %u\n", server->url(), client->id());
+ } else if(type == WS_EVT_ERROR){
+ //error was received from the other end
+ os_printf("ws[%s][%u] error(%u): %s\n", server->url(), client->id(), *((uint16_t*)arg), (char*)data);
+ } else if(type == WS_EVT_PONG){
+ //pong message was received (in response to a ping request maybe)
+ os_printf("ws[%s][%u] pong[%u]: %s\n", server->url(), client->id(), len, (len)?(char*)data:"");
+ } else if(type == WS_EVT_DATA){
+ //data packet
+ AwsFrameInfo * info = (AwsFrameInfo*)arg;
+ if(info->final && info->index == 0 && info->len == len){

+ os_printf("ws[%s][%u] %s-message[%llu]: ", server->url(), client->id(), (info->opcode == WS_TEXT)?"text":"binary", info->len);
+ if(info->opcode == WS_TEXT){

+ os_printf("%s\n", (char*)data);
+ } else {
+ for(size_t i=0; i < info->len; i++){
+ os_printf("%02x ", data[i]);
+ }
+ os_printf("\n");
+ }
+ if(info->opcode == WS_TEXT)
+ client->text("I got your text message");
+ else
+ client->binary("I got your binary message");
+ } else {
+ //message is comprised of multiple frames or the frame is split into multiple packets
+ if(info->index == 0){
+ if(info->num == 0)
+ os_printf("ws[%s][%u] %s-message start\n", server->url(), client->id(), (info->message_opcode == WS_TEXT)?"text":"binary");
+ os_printf("ws[%s][%u] frame[%u] start[%llu]\n", server->url(), client->id(), info->num, info->len);
+ }
+
+ os_printf("ws[%s][%u] frame[%u] %s[%llu - %llu]: ", server->url(), client->id(), info->num, (info->message_opcode == WS_TEXT)?"text":"binary", info->index, info->index + len);
+ if(info->message_opcode == WS_TEXT){
+ data[len] = 0;
+ os_printf("%s\n", (char*)data);
+ } else {
+ for(size_t i=0; i < len; i++){
+ os_printf("%02x ", data[i]);
+ }
+ os_printf("\n");
+ }
+
+ if((info->index + len) == info->len){
+ os_printf("ws[%s][%u] frame[%u] end[%llu]\n", server->url(), client->id(), info->num, info->len);
+ if(info->final){
+ os_printf("ws[%s][%u] %s-message end\n", server->url(), client->id(), (info->message_opcode == WS_TEXT)?"text":"binary");
+ if(info->message_opcode == WS_TEXT)
+ client->text("I got your text message");
+ else
+ client->binary("I got your binary message");
+ }
+ }
+ }
+ }
+}
+```
+
+### Methods for sending data to a socket client
+```cpp
+
+
+
+//Server methods
+AsyncWebSocket ws("/ws");
+//printf to a client
+ws.printf((uint32_t)client_id, arguments...);
+//printf to all clients
+ws.printfAll(arguments...);
+//printf_P to a client
+ws.printf_P((uint32_t)client_id, PSTR(format), arguments...);
+//printfAll_P to all clients
+ws.printfAll_P(PSTR(format), arguments...);
+//send text to a client
+ws.text((uint32_t)client_id, (char*)text);
+ws.text((uint32_t)client_id, (uint8_t*)text, (size_t)len);
+//send text from PROGMEM to a client
+ws.text((uint32_t)client_id, PSTR("text"));
+const char flash_text[] PROGMEM = "Text to send"
+ws.text((uint32_t)client_id, FPSTR(flash_text));
+//send text to all clients
+ws.textAll((char*)text);
+ws.textAll((uint8_t*)text, (size_t)len);
+//send binary to a client
+ws.binary((uint32_t)client_id, (char*)binary);
+ws.binary((uint32_t)client_id, (uint8_t*)binary, (size_t)len);
+//send binary from PROGMEM to a client
+const uint8_t flash_binary[] PROGMEM = { 0x01, 0x02, 0x03, 0x04 };
+ws.binary((uint32_t)client_id, flash_binary, 4);
+//send binary to all clients
+ws.binaryAll((char*)binary);
+ws.binaryAll((uint8_t*)binary, (size_t)len);
+//HTTP Authenticate before switch to Websocket protocol
+ws.setAuthentication("user", "pass");
+
+//client methods
+AsyncWebSocketClient * client;
+//printf
+client->printf(arguments...);
+//printf_P
+client->printf_P(PSTR(format), arguments...);
+//send text
+client->text((char*)text);
+client->text((uint8_t*)text, (size_t)len);

+//send binary from PROGMEM
+const uint8_t flash_binary[] PROGMEM = { 0x01, 0x02, 0x03, 0x04 };
+client->binary(flash_binary, 4);
+```
+
+### Direct access to web socket message buffer
+When sending a web socket message using the above methods a buffer is created. Under certain circumstances you might want to manipulate or populate this buffer directly from your application, for example to prevent unnecessary duplications of the data. This example below shows how to create a buffer and print data to it from an ArduinoJson object then send it.
+
+```cpp
+void sendDataWs(AsyncWebSocketClient * client)
+{
+ DynamicJsonBuffer jsonBuffer;
+ JsonObject& root = jsonBuffer.createObject();
+ root["a"] = "abc";
+ root["b"] = "abcd";
+ root["c"] = "abcde";
+ root["d"] = "abcdef";
+ root["e"] = "abcdefg";
+ size_t len = root.measureLength();
+ AsyncWebSocketMessageBuffer * buffer = ws.makeBuffer(len); // creates a buffer (len + 1) for you.
+ if (buffer) {
+ root.printTo((char *)buffer->get(), len + 1);
+ if (client) {
+ client->text(buffer);
+ } else {
+ ws.textAll(buffer);
+ }
+ }
+}
+```
+
+### Limiting the number of web socket clients
+Browsers sometimes do not correctly close the websocket connection, even when the close() function is called in javascript. This will eventually exhaust the web server's resources and will cause the server to crash. Periodically calling the cleanClients() function from the main loop() function limits the number of clients by closing the oldest client when the maximum number of clients has been exceeded. This can called be every cycle, however, if you wish to use less power, then calling as infrequently as once per second is sufficient.
+
+```cpp
+void loop(){
+ ws.cleanupClients();
+}
+```
+
+
+## Async Event Source Plugin
+The server includes EventSource (Server-Sent Events) plugin which can be used to send short text events to the browser.
+Difference between EventSource and WebSockets is that EventSource is single direction, text-only protocol.
+
+### Setup Event Source on the server
+```cpp
+AsyncWebServer server(80);
+AsyncEventSource events("/events");
+
+void setup(){
+ // setup ......
+ events.onConnect([](AsyncEventSourceClient *client){
+ if(client->lastId()){
+ Serial.printf("Client reconnected! Last message ID that it gat is: %u\n", client->lastId());
+ }
+ //send event with message "hello!", id current millis
+ // and set reconnect delay to 1 second
+ client->send("hello!",NULL,millis(),1000);
+ });
+ //HTTP Basic authentication
+ events.setAuthentication("user", "pass");
+ server.addHandler(&events);
+ // setup ......
+}
+
+void loop(){
+ if(eventTriggered){ // your logic here
+ //send event "myevent"
+ events.send("my event content","myevent",millis());
+ }
+}
+```
+
+### Setup Event Source in the browser
+```javascript
+if (!!window.EventSource) {
+ var source = new EventSource('/events');
+
+ source.addEventListener('open', function(e) {
+ console.log("Events Connected");
+ }, false);
+
+ source.addEventListener('error', function(e) {
+ if (e.target.readyState != EventSource.OPEN) {
+ console.log("Events Disconnected");
+ }
+ }, false);
+
+ source.addEventListener('message', function(e) {
+ console.log("message", e.data);
+ }, false);
+
+ source.addEventListener('myevent', function(e) {
+ console.log("myevent", e.data);
+ }, false);
+}
+```
+
+## Scanning for available WiFi Networks
+```cpp
+//First request will return 0 results unless you start scan from somewhere else (loop/setup)
+//Do not request more often than 3-5 seconds
+server.on("/scan", HTTP_GET, [](AsyncWebServerRequest *request){
+ String json = "[";
+ int n = WiFi.scanComplete();
+ if(n == -2){
+ WiFi.scanNetworks(true);
+ } else if(n){
+ for (int i = 0; i < n; ++i){
+ if(i) json += ",";
+ json += "{";
+ json += "\"rssi\":"+String(WiFi.RSSI(i));
+ json += ",\"ssid\":\""+WiFi.SSID(i)+"\"";
+ json += ",\"bssid\":\""+WiFi.BSSIDstr(i)+"\"";
+ json += ",\"channel\":"+String(WiFi.channel(i));
+ json += ",\"secure\":"+String(WiFi.encryptionType(i));
+ json += ",\"hidden\":"+String(WiFi.isHidden(i)?"true":"false");
+ json += "}";
+ }
+ WiFi.scanDelete();
+ if(WiFi.scanComplete() == -2){
+ WiFi.scanNetworks(true);
+ }
+ }
+ json += "]";
+ request->send(200, "application/json", json);
+ json = String();
+});
+```
+
+## Remove handlers and rewrites
+
+Server goes through handlers in same order as they were added. You can't simple add handler with same path to override them.
+To remove handler:
+```arduino
+// save callback for particular URL path
+auto handler = server.on("/some/path", [](AsyncWebServerRequest *request){
+ //do something useful
+});
+// when you don't need handler anymore remove it
+server.removeHandler(&handler);
+
+// same with rewrites
+server.removeRewrite(&someRewrite);
+
+server.onNotFound([](AsyncWebServerRequest *request){
+ request->send(404);
+});
+
+// remove server.onNotFound handler
+server.onNotFound(NULL);
+
+// remove all rewrites, handlers and onNotFound/onFileUpload/onRequestBody callbacks
+server.reset();
+```
+
+## Setting up the server
+```cpp

+ }
+ static char temp[128];
+ sprintf(temp, "Seconds since boot: %u", millis()/1000);

+}
+```
+
+### Setup global and class functions as request handlers
+
+```cpp
+#include
+#include
+#include
+#include
+
+void handleRequest(AsyncWebServerRequest *request){}
+
+class WebClass {
+public :
+ AsyncWebServer classWebServer = AsyncWebServer(81);
+
+ WebClass(){};
+
+ void classRequest (AsyncWebServerRequest *request){}
+
+ void begin(){
+ // attach global request handler
+ classWebServer.on("/example", HTTP_ANY, handleRequest);
+
+ // attach class request handler
+ classWebServer.on("/example", HTTP_ANY, std::bind(&WebClass::classRequest, this, std::placeholders::_1));
+ }
+};
+
+AsyncWebServer globalWebServer(80);
+WebClass webClassInstance;
+
+void setup() {
+ // attach global request handler
+ globalWebServer.on("/example", HTTP_ANY, handleRequest);
+
+ // attach class request handler
+ globalWebServer.on("/example", HTTP_ANY, std::bind(&WebClass::classRequest, webClassInstance, std::placeholders::_1));
+}
+
+void loop() {
+
+}
+```
+
+### Methods for controlling websocket connections
+
+```cpp
+ // Disable client connections if it was activated
+ if ( ws.enabled() )
+ ws.enable(false);
+
+ // enable client connections if it was disabled
+ if ( !ws.enabled() )
+ ws.enable(true);
+```
+
+Example of OTA code
+
+```cpp
+ // OTA callbacks
+ ArduinoOTA.onStart([]() {
+ // Clean SPIFFS
+ SPIFFS.end();
+
+ // Disable client connections
+ ws.enable(false);
+
+ // Advertise connected clients what's going on
+ ws.textAll("OTA Update Started");
+
+ // Close them
+ ws.closeAll();
+
+ });
+
+```
+
+### Adding Default Headers
+
+In some cases, such as when working with CORS, or with some sort of custom authentication system,
+you might need to define a header that should get added to all responses (including static, websocket and EventSource).
+The DefaultHeaders singleton allows you to do this.
+
+Example:
+
+```cpp
+DefaultHeaders::Instance().addHeader("Access-Control-Allow-Origin", "*");
+webServer.begin();
+```
+
+*NOTE*: You will still need to respond to the OPTIONS method for CORS pre-flight in most cases. (unless you are only using GET)
+
+This is one option:
+
+```cpp
+webServer.onNotFound([](AsyncWebServerRequest *request) {
+ if (request->method() == HTTP_OPTIONS) {
+ request->send(200);
+ } else {
+ request->send(404);
+ }
+});
+```
+
+### Path variable
+
+With path variable you can create a custom regex rule for a specific parameter in a route.
+For example we want a `sensorId` parameter in a route rule to match only a integer.
+
+```cpp
+ server.on("^\\/sensor\\/([0-9]+)$", HTTP_GET, [] (AsyncWebServerRequest *request) {
+ String sensorId = request->pathArg(0);
+ });
+```
+*NOTE*: All regex patterns starts with `^` and ends with `$`
+
+To enable the `Path variable` support, you have to define the buildflag `-DASYNCWEBSERVER_REGEX`.
+
+
+For Arduino IDE create/update `platform.local.txt`:
+
+`Windows`: C:\Users\(username)\AppData\Local\Arduino15\packages\\`{espxxxx}`\hardware\\`espxxxx`\\`{version}`\platform.local.txt
+
+`Linux`: ~/.arduino15/packages/`{espxxxx}`/hardware/`{espxxxx}`/`{version}`/platform.local.txt
+
+Add/Update the following line:
+```
+ compiler.cpp.extra_flags=-DDASYNCWEBSERVER_REGEX
+```
+
+For platformio modify `platformio.ini`:
+```ini
+[env:myboard]
+build_flags =
+ -DASYNCWEBSERVER_REGEX
+```
+*NOTE*: By enabling `ASYNCWEBSERVER_REGEX`, `` will be included. This will add an 100k to your binary.
