about ajax,Coming clean about Ajax

摘要：

The article presents information on the use of Ajax technology in computer applications. Ajax is not a technology but a mix of HTML, CSS, Javascript and XML. It takes advantage of powerful new features found in popular web browsers. Ajax makes web sites more interactive, giving them the look and feel of traditional desktop applications. The principles behind Ajax can be traced back to Microsoft's Remote Scripting in 1998, although other references point to the ability of browsers to load web page content without requiring a full web page reload as far back as 1996/1997 in IE2 and Netscape 4. Ajax removes the need for desktop applications. Ajax technology allows browser to communicate with the server asynchronously. Therefore, the user can continue to use the web application rather than waiting for a response. One of the benefits of using Ajax web applications include software updates. An Ajax engine adds an extra layer between the user and the server. The engine is loaded automatically when the web application is started and is responsible both for communicating with the server and for rendering the browser web page.
