Hi,
i default.vcl change :

# Did not cache the admin and login pages
if (req.url ~ "/wp-(login|admin)") {
    return (pass);
}

By :

# Did not cache the admin and login pages
if (req.url ~ "/(s-login|tomer-login|wp-login|wp-admin)") {
    return (pass);
}

You can remove wp-login and wp-admin if you don't use them.
Regards.

anf if i delete Cookies from Chrome browser and after that i try to connect to admin area, he said this error:

ERROR: Cookies are blocked or not supported by your browser. Cookies must be enabled to use WordPress.

Have you custom the file varnish4-wordpress ?
I remember that I have similary error and I think these lines resolve it :

# Remove the wp-settings-1 cookie
set req.http.Cookie = regsuball(req.http.Cookie, "wp-settings-1=[^;]+(; )?", "");
# Remove the wp-settings-time-1 cookie
set req.http.Cookie = regsuball(req.http.Cookie, "wp-settings-time-1=[^;]+(; )?", "");
# Remove the wp test cookie
set req.http.Cookie = regsuball(req.http.Cookie, "wordpress_test_cookie=[^;]+(; )?", "");

I don't remember exactly which repair your problem but try to search all "cookie" occurence in varnish4-wordpress. =)

[TOMER628]

so just add this line to code?

[Oyabi]

yep, look at varnish4-wordpress ;)
https://github.com/nicolargo/varnish-nginx-wordpress/blob/master/varnish/varnish4-wordpress
Maybe anothers lines must be add, but there all in example file ;)

[TOMER628]

this exactly the code i copied ...
and also i added this line into file right now ,and still error with cookies

[TOMER628]

by the way this:

Only allow purging from specific IPs

acl purge {
"localhost";
"127.0.0.1";
}

i did not change the ip (127.0.0.1) this ok right ?

[Oyabi]

Sorry i haven't read all my file earlier.
You must also ahve theses lines in sub vcl_backend_response :

# Only allow cookies to be set if we're in admin area
if (beresp.http.Set-Cookie && bereq.url !~ "^/wp-(login|admin)") {
   unset beresp.http.Set-Cookie;
}

For your configuration you must change it to :

# Only allow cookies to be set if we're in admin area
if (beresp.http.Set-Cookie && bereq.url !~ "^/(s-login|tomer-login|wp-login|wp-admin)") {
   unset beresp.http.Set-Cookie;
}

I hope your error is gone.
127.0.0.1 and localhost are right in almost ever case ;)

[TOMER628]

yes !!!!!!
you did it !!!!

Great !

thank you so much

i think maybe you need to add this to your code ..
i mean to add explain if someone (like me) change the login admin area..

[Oyabi]

It's in the file, but you must adapt it to correpond to your custom install.
By default you can access wordpress admin with /wp-admin address.
You modify it for use (s-login|tomer-login) so you must add this change in config file ;)
Have a nice day.

thank you so much i like your code it make my Wordpress fastest

[TOMER628]

hi again..
i forgot to ask:
i need also this plugin (or your code do that automaticlly ?
LINK: https://wordpress.org/plugins/varnish-http-purge/

[nicolargo]

No, you had to use this plugin in order to purge the cache (for exemple after an WP plugins update).

[TOMER628]

SO the answer is not, right ?

[nicolargo]

Yes the answer is... not.
