Detecting close of client connect in node.js

Question

I am using node.js for long held connections. I want to know how I can detect when the client connection closes (maybe when the user closes the tab). How do I specify a callback for that?

Answering my own question - You can detect close of client connection by doing:

http.createServer(function(request, response) {    
    request.connection.addListener('close', function () {
        // callback is fired when connection closed (e.g. closing the browser)
    });
}
