Hi,
Is there a support for WebSocket sub-protocols? I can't find any reference for it.
As I understand, the client will send a separate 'Sec-WebSocket-Protocol:abc,def,xyz' header, and the server should respond with an appropriate response header, specifying the preferred protocol.
Unfortunately, inside the WebSocket handler delegate, I can't manipulate the http response headers - I guess, it's already sent.
