Would this be acceptable, or you think this empty reply is not worth fixing
this way?
The problem is that at this point (poll() loop), "101 Switching
Protocol" is already sent to the backend, and hence the
ap_proxy_pass_brigade() doing so in proxy_wstunnel_request() should
already have failed with the correct status code returned to the
handler.
Hm, I think I'm little bit confused how it's supposed to work. I thought
mod_proxy_wstunnel appends Upgrade and Connection header to the
request's headers, sends it to the backend and then the backend responds
with "101 Switching Protocols".
But when reading the code now, it would mean that "101 Switch Protocols"
is forwarded to the client, which, I think, should not happen.
Well, I will test it more with some real websocket server as a backend
to fully understand how it works.
Why isn't that happening?
