title: In socket.io, compression perMessageDeflate not working
body: <p>I see the headers present in both the request and the response</p>
  
  <pre><code>Sec-WebSocket-Extensions:permessage-deflate
  </code></pre>
  
  <p>and yet, the data sent over the socket is still the same( verified for large and small size data).</p>
  
  <p>Please clarify the following for me:</p>
  
  <ol>
  <li>Data sent in the frames of the socket should be compressed right?</li>
  <li>Will i be able to see the compressed data on the developer tools of chrome under the frames tab of the socket ?</li>
  </ol>
