Multi-player games in HTML5 : Socket.io on the server side with session

Server.js

io.sockets.on('connection', function (socket) {

		//create a new player, which registers its events
	var connection = new Session( socket );
		//add to the list of connections (for finding a game)
	server.addConnection( connection );

		//This will send a message to all clients saying that they connected,
		//And hand them their serverid for future interactions. 
	socket.emit('onConnect', { serverid : connection.serverid });
		
});
