Ajax uses familiar web technologies-DHTML, CSS, DOM, and JavaScript-in radically different ways resulting in a much richer user experience. The key to success lies in knowing how to orchestrate them as a coherent whole, splitting off parts of what is normally done by the server and putting it into the browser for instantaneous response to user input.
Ajax allows a new breed of web applications with the rich expressiveness of desktop applications.This book helps developers realize that promise-it explains the big picture and how to unlearn many old coding habits. It explains the design patterns and best practices to create a live interface for the user, not get in his way.
It also discusses important Ajax issues: how to make good use of network bandwidth, and how to identify, and avoid, common Ajax pitfalls.http://rapidshare.com/files/52371967/1932394613.zip
