Ajax is an all-encompassing term surrounding the use of asynchronous HTTP requests initiated by
requests may be executed in any number of ways and using any number of different data transmission
formats. Combining this remote data retrieval with the interactivity of the Document Object Model
(DOM) has bred a new generation of web applications that seem to defy all the traditional rules of what

specifically towards the goal of creating web applications that look and behave like desktop applications.
This book covers the various aspects of Ajax, including the different ways you can initiate HTTP
requests to the server and the different formats that can be used to carry data back and forth. You will
learn different Ajax techniques and patterns for executing client-server communication on your web site
and in web applications.
