title: Connecting to Socket.IO server hosted on Azure Mobile Services returns Error
body: <p>I am attempting to connect to a Socket.IO server hosted in the extension folder of my Azure Mobile service using the startup script, although I am unable to do so, and receive the error:     </p>
  
  <p><code>"WebSocket connection to 'ws://mymobileservice.azure-mobile.net/extensions/socket.io/?EIO=2&amp;transport=websocket' failed: Error during WebSocket handshake: Unexpected response code: 503"</code></p>
  
  <p>I am using port 80 with a path of 'extensions/socket.io'
  I've also used port 443 with a secure connection, and that has yielded the same error.</p>
  
  <p>Am I on the right track?
  Any help is greatly appreciated.</p>
