I am trying to set up a test environment client--HTTP/2-->proxy--HTTP/2-->server. The client sends a POST request that contains a large body, and the response also contains a large body. I need the server to start sending response as soon as it receives POST request header, so that both sides are sending data to each other concurrently. Is it possible to add a function into server to support sending early response?

This already works. See #13444 etc. In particular #13444 (comment) has a demo.

There's a live demo at https://http2.golang.org/ (see the /ECHO handler linked there) that streams its input back capitalized.

That demo code is https://github.com/golang/net/blob/master/http2/h2demo/h2demo.go (search for "echo").
