Comet - long-polling using Ajax

I just wanted to save this video for any references wanted to understand what Comet is.






So what exactly Comet is? Comet is still using AJAX but its just a technique done in the server. It uses timestamp for comparison of updates, then AJAX request will have just to wait until the server will response, so it's the sever will have to push data to the browser. This is a long-polling method and can save traffic than running an AJAX request from time-to-time.
