Ajax !

Ajax (asynchronous JavaScript and XML), or AJAX, is a group of interrelated web development techniques used for creating interactive web applications or rich Internet applications. With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.[1] Data is retrieved using the XMLHttpRequest object or through the use of Remote Scripting in browsers that do not support it. Despite the name, the use of JavaScript, XML, or asynchrony is not required.


While the term Ajax was coined in 2005,[4] techniques for the asynchronous loading of content date back to 1996, when Internet Explorer introduced the IFrame element.[5] Microsoft's Remote Scripting, introduced in 1998, acted as a more elegant replacement for these techniques, with data being pulled in by a Java applet with which the client side could communicate using JavaScript. In 1999, Microsoft created the XMLHttpRequest object as an ActiveX control in Internet Explorer 5, and developers of Mozilla and Safari followed soon after with native versions of the object.[6][5] On April 5, 2006 the World Wide Web Consortium (W3C) released the first draft specification for the object in an attempt to create an official web standard.[7]
