title: Does socket.io have raw WebSocket access like sockjs?
body: <p><a href="https://github.com/sockjs/sockjs-node" rel="nofollow">Sockjs</a> and <a href="http://socket.io/" rel="nofollow">socket.io</a> are both JavaScript libraries for node.js that automatically choose which transport protocol can be used on top of HTTP.</p>
  
  <p>I know that sockjs also provides a direct WebSocket access, so a sockjs server can be used with the associated socksjs client library or with a native WebSocket access.</p>
  
  <p>For instance, if I have a sockjs-based server at <code>http://localhost:8081/echo</code> I can use a direct WebSocket access with the URL <code>ws://localhost:8081/echo/websocket</code></p>
  
  <p>Does socket.io also provide a direct/raw WebSocket access?</p>
