I have created simple chat application using node.js + socket.io. When I try to run it, it does not run as expected: it is continually sending requests from the client. I have configured setting of transports: ['jsonp-polling', 'xhr-polling'] in both (client/sever) side. I tried setting ['close timeout': 10], but this did not change anything. I don't understand what is happening here.
I think my connection in broken, as I see in the log file (at the end).
following is the my code :
server side : app.js ~~~~~~~~~~~~~~~~~~~~
var sio = require('socket.io');
var io = sio.listen(app)
io.configure(function () {
io.enable('browser client minification');
io.enable('browser client etag');
io.enable('browser client gzip');
io.set('log level', 3);
});
io.on('connection', function (client) {
client.on('message', function (msg) {
socket.broadcast(msg);
});
client.on('disconnect', function () {
});
});
client side : index.html ~~~~~~~~~~~~~~~~~~~~~~~~
<!DOCTYPE html>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>

$(document).ready(function () {
var socket = new io.Socket("localhost", {port: 8080});
socket.on('connect', function () {
socket.send('A client connected.');
});
socket.on('message', function (message) {
$('div#messages').append($('<p>'), message);
});
socket.on('disconnect', function () {
console.log('disconnected');
});
socket.connect();
$('input').keydown(function (event) {
if(event.keyCode === 13) {
socket.send($('input').val());
$('input').val('');
}
});
});
</script>
</head>
<body>
<input type="text" style="width: 300px;" />
<div id="messages" style="border:solid 1px #000;"> </div>
</body>
</html>
Here is the log file:

Could anyone suggest how to debug this problem or what the problem actually is?
