Introduction
AJAX
AJAX stands for asynchronous JavaScript and XML. AJAX is the technique of exchanging data with a server, and updating parts of a web page, without reloading the whole page. AJAX is a method of building interactive applications for the Web that process user requests immediately. Ajax combines several programming tools including JavaScript, DHTML, CSS, XML, DOM and the Microsoft object XMLHttpRequest. Google Maps (a product of Google) is one well-known application that uses Ajax.
