AppFog node.js client cannot load socket.io

Question

I just deployed a node.js site to AppFog. It works fine locally when I go to "http://localhost:8080", but when I got to the one on AppFog: http://bandwithfriends.aws.af.cm/ I get the following Chrome console error:

XMLHttpRequest cannot load http://localhost:8080/socket.io/1/?t=1357769454152. Origin http://bandwithfriends.aws.af.cm is not allowed by Access-Control-Allow-Origin.

SERVER CODE:

var app = require('http').createServer(handler),
    io = require('socket.io').listen(app),
    static = require('node-static'); // for serving files

// This will make all the files in the current folder
// accessible from the web
var fileServer = new static.Server('./');


app.listen(process.env.VCAP_APP_PORT || 8080);

io.configure('development', function(){
  io.set('transports', ['xhr-polling']);
});

CLIENT CODE index.html: I am including socket.io like this:

<script src="/socket.io/socket.io.js"></script>

CLIENT CODE script.js:

var url = 'http://localhost:8080';
var socket = io.connect(url);

How do I fix this?

Answer 1

All I had to do to fix this was remove the url on the client side code:

var socket = io.connect();

Hope this helps anyone else having the same problem!
