Simple nodeJS example not working with socket.io

Have been struggling all day trying to make this simple example work using socket.io. I've tried initially on Windows 7 with Cygwin. Have since also tried on OS X, with the same result.

When running the script, it shows this...

2 May 20:57:47 - socket.io ready - accepting connections

But visiting the index.html page doesnt show a client has even connected.

index.html

<html>
<head>
<script type="text/javascript" src="socket.io.js"></script> 
<script type="text/javascript"> 
    var socket = new io.Socket('localhost',{'port':8090});

    socket.connect();

    socket.on('connect', function(){
        console.log('connected');
        socket.send('hi!'); 
    });

    socket.on('message', function(data){ 
        console.log('message recived: ' + data);
    });

    socket.on('disconnect', function(){
        console.log('disconected');
    });
</script> 
</head>
<body></body>
</html>

server.js

var http = require('http'), io = require('socket.io'),

server = http.createServer(function(req, res){ 
    res.writeHead(200, {'Content-Type': 'text/html'}); 
    res.end('<h1>Hello world</h1>'); 
});
server.listen(8090);

var socket = io.listen(server); 
socket.on('connection', function(client){ 
    console.log('client connected');

    client.on('message', function(){ 
        console.log('message arrive');
        client.send('some message');
    });

    client.on('disconnect', function(){
        console.log('connection closed');
    });
});

Any ideas on what I could be doing wrong? No console messages whatsoever are being displayed. Notably, when i use Firebug to look at the index.html page, no scripts are being embedded, which is odd..Not sure what could be causing that.
