How AJAX Works: 10 Practical Uses For AJAX

[uriel]

AJAX has gotten more and more popular over the years, and has allowed web applications to act more and more like desktop applications. AJAX can provide a lot of additional functionality that could not be accomplished any other way.

Nice, quick synopsis of AJAX. There's a lot it can be used for aside from these examples, though. I'm interested to see how the concepts evolve with new browser improvements and the progression of HTML5.

The back side of ajax which bothers me most is that you cant go back into history pages, everything is happening on one single page.

Yeah, it is one problem that needs to be solved. But, except for this problem, ajax offers truly enjoyable web browsing. Imagine how would it be like to come back on the registration page again and again because usernames were already taken (only one of the many)!

Only problem with that tutorial is that meebo chat doesn't use AJAX, it uses COMET, which is almost the same. With AJAX you just have 1 request to the server followed by 1 response, this request is immediately closed after it's sent, and the response is immediately sent. It's therefore unsuited to chat because in order to have a live chat you would have to constantly poll the server in order to get the latest messages. COMET is usually used instead because it allows for responses from the server to not be sent until the server says "ok i got a message from Guy A, ill send it back to Guy B who I've been waiting to send something to". This, therefore, allows for less connections to the server over time and a more asynchronous chat, since your not constantly polling the server for updates.

I'm not very good at explaining things, so here's more info on COMET
