You can connect using the GData APIs to get your calendar information, etc. over HTTP today. You can do that despite the fact that HTTP doesn't support a subprotocol defining what that API looks like. It works because you read the docs and wrote code to speak the "subprotocol" over that connection, despite the fact that it wasn't announced. Likewise, you could do exactly the same in WS whether or not a hypothetical GData service over WebSocket used a subprotocol. > A protocol MUST NOT be designed taking that wrong assumption into > account.

To me, that limits the value of subprotocol as out-of-band identification of what the next layer up plans to do with that channel, similar to a MIME type for HTTP. I don't see where your suggestion this is a Javascript feature enters into it. > Of course, what you propose is just valid for allowing a stupid JS > developer coding a JS application that connects to the WS server by > providing "Sec-WebSocket-Protocol: > i-dont-know-programming.but-i-am-cool.com".
