Feature Request: HTTP Connect Client

[fortuna]

We currently have SOCKS5 and Shadowsocks clients, and a HTTP CONNECT handler, but not an HTTP CONNECT client. It would be helpful to have one.

Enhancements:

• Support H2
• Support H3
• Support CONNECT-UDP (see x/net/http2: support proxying udp in HTTP/2 with RFC 9298 golang/go#67860)

Hi!

I would like to take on this task, if possible.

May I ask you if I got the task right?

• Implement a transport.StreamDialer that does a CONNECT request
• Implement a http.Handler and a transport.StreamDialer (like the above) for CONNECT-UDP

[fortuna]

That sounds reasonable, but they are really two separate tasks that don't need to be conflated.

We will also need a CONNECT-UDP client, which is another task.

@fortuna , hi!
Would you like to take a look at an HTTP/1.1 implementation: #350?

[nikolaikabanenkov]

Now that we have a basic HTTP CONNECT client, we can consider enhancements.

• Extend the current HTTP CONNECT client to support TLS and HTTP/2.
• Create a special constructor for HTTP/3, since HTTP/3 uses QUIC over a packet connection and should therefore accept a PacketDialer instead of a StreamDialer. Add support for HTTP/3 in this special case.

Does this sound reasonable to you?
