AJAX

Asynchronous JavaScript and XML

AJAX is not a new programming language, but a new technique for creating better, faster, and more interactive web applications.


With AJAX, a JavaScript can communicate directly with the server, with the XMLHttpRequest object. With this object, a JavaScript can trade data with a web server, without reloading the page.


AJAX uses asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages.


AJAX is based on the following web standards:

JavaScript
XML
HTML
CSS

AJAX applications are browser- and platform-independent.
