Recently, I have been experimenting with Node.js and Socket.io. Successfully, I have been able to implement these but only on localhost. Now I would like use this functionality on my dedicated server. I am hosting my server from my own home and I cannot get node and socket to run outside of localhost. The importance of this is so that I can use two different computers while testing out my site. Here is my code as follows:

```
app.js:

   var app = require('express')()
  , server = require('http').createServer(app)
  , io = require('socket.io').listen(server);

server.listen(80);

app.get('/', function (req, res) {
  res.sendfile(__dirname + '/index.html');
});

io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    console.log(data);
  });
});

```

```
index.html:

    <script src="http://localhost:8080/socket.io/socket.io.js"></script>
    <script>
      var socket = io.connect('http://localhost:8080');
      socket.on('news', function (data) {
        console.log(data);
        socket.emit('my other event', { my: 'data' });
      });

</script>

```

These are samples that were taken directly off the socket.io site. Now it works on localhost, but not externally. I cannot use it on another computer. I was advised to change 
```
`var socket = io.connect('http://localhost:8080');`
```
 to

```
`var socket = io.connect('http://mydomain.com:8080');`
```
, but that makes the browser throw the following errors : 

```
 Uncaught ReferenceError: io is not defined mydomain.com/:3
    GET http://mydomain.com/socket.io/socket.io.js  mydomain.com/:1

```

even on my main server computer. Im using OSX server with a mac mini btw.

Any advice would be appreciated:
