commit 1dd0da7ef968f914cc99137cf98852d77351a174 Author: David Fifield david@bamsoftware.com Date: Sun Jul 22 20:53:53 2012 -0700

Don't let websockify send "Sec-WebSocket-Protocol: binary".

We patch websockify so that it assumes binary transport when no subprotocol is given. Previously we continued to send a "Sec-WebSocket-Protocol: binary" in our response, which is a violation of section 4.2.2 of RFC 6455: "The value chosen MUST be derived from the client's handshake, specifically by selecting one of the values from the |Sec-WebSocket-Protocol| field that the server is willing to use for this connection (if any). If the client's handshake did not contain such a header field or if the server does not agree to any of the client's requested subprotocols, the only acceptable value is null." Chromium (version 20, I believe) started being more strict about enforcing this, which caused the relay connection to fail.
