title: Could websocket support gzip compression?
body: <p>After the success handshake of WebSocket, could we used gzip compression?</p>
  
  <p>Here are my tests:  </p>
  
  <ol>
  <li>I use autobahn lib to build a server, then respon to client as:<br>
  <code>HTTP/1.1 101 Switching Protocols   content-encoding: gzip   Connection: Upgrade   Server: AutobahnPython/?.?.?   Upgrade:
  WebSocket   Sec-WebSocket-Accept: RIR8KmljoV8Cv9mdiLY7GM2nYMc=</code> </li>
  <li>then my server uses gzip compression  </li>
  <li>and the chrome browser got the result, but it told me that "could not decode a text frame as UTF-8"</li>
  </ol>
