node.js - Socket io not working under Express project on heroku -

-

the contents of app.js 

  var express =require('express'),     app =express();     server=require('http').createserver(app),     io =require ('socket.io').listen(server);     io.configure(function () {          io.set("transports", ["xhr-polling"]);          io.set("polling duration", 10);          });      users = {};     var port = process.env.port || 5000;      server.listen(port);     app.use(express.static(__dirname + '/public'));       io.set('log level',1); io.sockets.on('connection', function(socket){ console.log("hey");     socket.on('new user', function(data, callback){         if (data in users){             console.log("hey");             callback(false);         } else{             callback(true);             console.log("hey1");             socket.nickname = data;             users[socket.nickname] = socket;             updatenicknames();         }     }); . . . .

in public/index.html

$(document).ready(function(){   var socket = io.connect(); . .

the index.html gets loaded ... typically mine app basic chat app url http://chat-up.herokuapp.com/

so first step user name , check if username taken

the url changes http://chat-up.herokuapp.com/ http://chat-up.herokuapp.com/?

my guess sockets aren't working

what doing wrong or there way ?

thank
