Ajax has been out for some time now, without any substantial changes, improvement and the like. Well, as time seems to be near an Ajax 2.0 evolution, this firstPress deals with the emerging Comet and Reverse Ajax technologies that could arguably later define part of the next generation Ajax 2.0.

Comet and Reverse Ajax: The Next Generation Ajax 2.0 is the first and only book of its kind covering Comet and Reverse Ajax in this detail.

Written by Ajax expert and best selling author, Dave Crane, this book is a practical, hands-on resource for developers who want to preview and even use some of what will likely be in the next hot Ajax 2.0 release.

This review is from: Comet and Reverse Ajax: The Next-Generation Ajax 2.0 (Firstpress) (Paperback)

The authors do an excellent job of illustrating the "Comet" process here: Keeping an HTTP request open so that the client can continue to receive content from the server continuously, rather than having to repeatedly query the server for Ajax content. They describe the advantages and potential pitfalls in a good amount of depth without becoming overly detailed for programmers working with a Java framework like Grails. They talk especially about DWR, a fine framework that takes care of the details of Comet and can be easily used in conjunction with other web frameworks.

But before you invest in this book, you should be aware of two things: It's very short (like all of the Firstpress books) and only talks about DWR 2.0, while the cutting edge is DWR 3.0. Also, you should think about whether you really need Comet in order to do what you're doing; for most purposes, ordinary Ajax is fine. If you're trying to learn Comet in depth, the DWR documentation is a better resource. And if you're intent on learning Comet quickly, the eBook version of this book might be a better buy.

This review is from: Comet and Reverse Ajax: The Next-Generation Ajax 2.0 (Firstpress) (Paperback)

I've found this book very valuable source written by smart developers, It illustrate Comet aka reverse ajax 2.0 step by step and wrap my mind around all the problems and solutions during comet apps development. Comet is still immature technology but once you read the book you can apply it today in your web apps and achieve collaboration and real-time notification apps using the same technologies you use every day in your job in addition to some HTTP and XHR hacks , although the application ( Magnetic poetry )used to illustrate the technology isnot real world but it succeed in showing how to implement poll, push and biggybacking , long polling and Comet very easy , The rest of the book illustrate using server frameworks like DWR for easy comet , although iam a PHP fan i could apply all DWR concepts easy , then illustrate DoJo comet client-side framework and bayuex protocol , and end up with magnetic poetry appplication using all the techniques in the book , i recommend this book for all front-end engineers :)
