Using HTTP Proxy: Retrieved Host is IP Address instead of Domain in HTTPS Tracker URL

[bearx3f]

Please provide the following information

libtorrent version (or branch): 2.0.10

platform/architecture: qbittorrent-static-nox x86_64

compiler and compiler version: GCC 13.2.0 -- x86_64-linux-musl

I'm using qbittorrent and having http proxy settings

And when announce to HTTPS Tracker Libtorrent does not send the Host header in CONNECT requests to HTTPS trackers.

[arvidn]

correct. the CONNECT command optionally includes Proxy-Authorization:, but not the hostname of the destination.

The Host header is sent inside the SSL tunnel, to the destination server.

Is there a problem? Does the proxy need to know the hostname (as opposed to just the IP address) of the destination server?

[bearx3f]

there's a problem to sign the ssl connection in mitm mode proxy without hostname

[arvidn]

I'm intrigued. What's the feature or utility that's enabled by the proxy man-in-the-middling the connection?

You would also have to install their SSL cert for libtorrent to pick up as well. Is that a certification signed for all hostnames?

I'm tracking the download, upload, log event of the torrent, convert tracker response from any encoding to utf-8, and handle this incident #7653

Is that a certification signed for all hostnames?

Yes

and here verbose log from curl it's sent host in CONNECT

@bearx3f could you try this patch out?
#7710
