Simple comet ajax utility

cometjax

Project maintained on github.com/tenorviol/cometjax. Use it just like jQuery.ajax, same options.

$(function() {
	var comet = $.cometjax({
		url: "http://my.comet.server",
		success: function(data) {
			console.log(data);
		}
	});
	
	$("button.stop_comet").click(function() {
		comet.stop();
	});
});

This will poll the ajax query over and over again. Clicking the stop_comet button stops the incessant polling.

whoami example

whoami is a very rudimentary long-polling comet chat server that runs on node.js. To run the whoami example, download and install node.js. The server should run as is:

node example/whoami.node.js

Then launch whoami.html into various browser windows, and start chattin'.

Features

• Exactly like $.ajax, except long-polling
• < 0.4kB
• On error, waits a random time to prevent thundering hordes
• Avoids the perpetual browser loading problem
