Combining tried-and-true CSS, XML, and JavaScript™ technologies, Ajax provides web developers with the ability to create more sophisticated and responsive user interfaces and break free from the "click-and-wait" standard that has dominated the web since its introduction.

This book discusses the range of request brokers (including the hidden frame technique, iframes, and XMLHttp) and explains when one should be used over another. You will also learn different Ajax techniques and patterns for executing client-server communication on your web site and in web applications. Each chapter builds on information in the previous chapters so that by the end of the book, you will have gained the practical knowledge necessary to implement your own Ajax solutions.
