Cutting Edge: Perspectives on ASP.NET AJAX

摘要

Unless you've spent the past 12 months disconnected from the Net—perhaps vacationing on a remote tropical island or participating in a reality game show—you should know a few things about AJAX.

And finally, you should understand what AJAX is made up of. It's not a technology, per se. Instead, it is a blanket term to indicate rich browser applications built using powerful combinations of client-side Web technologies that have been around for years, such as JavaScript, cascading style sheets (CSS), DHTML, and XMLHttpRequest.
