Description stesaunde 2023-02-25 08:08:39 UTC 
Not bootstrapping WebSockets with HTTP/2 per RFC 8441

1) Use mod_http2

2) Use mod_proxy_wstunnel 

3) Use mod_proxy_http2

The WebSockets went over HTTP/1.1 per RFC 7230.

The WebSockets should go over HTTP/2 per RFC 8441.

There doesn't appear to be sufficient documentation for correct configuration of WebSockets over HTTP/2 on any platform.
Comment 1 Stefan Eissing 2023-02-28 10:43:01 UTC 
WebSocket over HTTP/2 is not implemented. That might explain the lack of documentation.

If implemented would it be in mod_http2 and mod_proxy_http2? Or separated out as its own modules?
Comment 3 Stefan Eissing 2023-03-02 07:26:46 UTC 
Well, mod_http2 would need to implement the "front-end" part. The backend would then use the same mod_proxy mechanism as the http/1.1 parts, I assume.
