Connect to Socket.io from express code

socket.io-client.js

// At the top of routes.js

var io = require('socket.io-client');

// Later

socket = io.connect('http://localhost:9714', {headers: {'X-express-to-socket-password': 'some secret string'}});

//or
socket = io.connect('http://localhost:9714', {'query': 'express-to-socket-password=some secret string'});

// In either case... all I see  coming in at https://github.com/ozten/roomr/blob/master/server/sockets.js#L16 is
