Microsoft ASP.NET and AJAX: Architecting Web Applications - reference book

In this book, Esposito challenges readers to think beyond the "easy way to AJAX", which involves adding AJAX capabilities to a non-AJAX system designed in the old model of web development. Instead, he proposes an alternate, if more difficult, paradigm involving patterns and complexities - and culminating in a new, pure-AJAX architecture. You'll learn why far better solutions result from the second, more radical approach - and you'll get practical guidance on how to implement this architecture for Rich Internet Applications (RIAs).
