About this tutorial
This AJAX tutorial explains what AJAX is and demonstrates how you can use it.
This tutorial uses ColdFusion to perform the server-side code but you can use any language you like for the server-side code.
What is AJAX?
With traditional web applications, when users submit a form they have to wait around for the page to reload before seeing the results.
With AJAX, your application can dynamically populate a page (for example, retrieve data from a database) without having to reload the page.
