x/net/http2: ability to access raw HTTP/2 stream

[JensRantil]

I am interested in creating a HTTP proxy (note: not a reverse proxy) in Go. I'm only interested in implementing the CONNECT method. All other methods are irrelevant for me. https://github.com/elazarl/goproxy comes very close to what I want to do, but I'm also interested in supporting CONNECT when client is connected to proxy using HTTP/2. AFAIK, according to RFC7540, CONNECT over HTTP/2 should work by hijacking the stream and do TCP tunneling over it.

*http2responseWriter does not implement http.Hijacker. One idea, would be that it implements http.Hijacker which will give access not to the underlying TCP connection but rather the HTTP stream.

...or is there any other approach I could take without having to implement low-level HTTP/2 stuff?

@agnivade Maybe I should have phrased it differently, then. See this as a feature request being able to access a raw stream in HTTP/2.

[agnivade]

Ok.

Any updates on this? It'd be very useful to have in order to build proxies that work for HTTP/2 too!

I am also interested in hijacking http2 streams for a tunnel solution based on individual http2 streams. Already created a fork which allows to hijack a http2 stream in the handle method https://github.com/becheran/net. I guess it would make sense to not use the original http.Hijacker interface but something stream specific instead to not be confused.

Will this ever be a feature in the http2 lib?
