Description

I found it when tried to use it as client with proxy.
When connecting to proxy websocket-sharp sends CONNECT request to proxy with request-target's authority component not equal to Host header (if port is 80), while RFC 7230, section 5.4: Host states:

If the target URI includes an authority component, then a
client MUST send a field-value for Host that is identical to that
authority component, excluding any userinfo subcomponent and its "@"
delimiter (Section 2.7.1).

So, to match rfc7230 definition port == 80 check in this line should be removed

Research direction

Start in HttpRequest.cs at the linked line around 125 and inspect how the proxy CONNECT request-target and Host header are assembled. Confirm the RFC 7230 requirement for port 80, then verify that the generated CONNECT request uses matching authority values.
