an introduction to Ajax

AJAX stands for Asynchronous JavaScript And XML.AJAX is a type of programming made popular in 2005 by Google (with Google Suggest).AJAX is not a new programming language, but a new way to use existing standards.

JavaScript communicates directly with the server, through the JavaScript XMLHttpRequest object

With an HTTP request, a web page can make a request to, and get a response from a web server - without reloading the page
When you start typing in Google's search box, a JavaScript sends the letters off to a server and the server returns a list of suggestions.
The XMLHttpRequest object is supported in Internet Explorer 5.0+, Safari 1.2, Mozilla 1.0 / Firefox, Opera 8+, and Netscape 7
The keystone of AJAX is the XMLHttpRequest object
