Comet and Reverse Ajax: The Next-Generation Ajax 2.0 (Firstpress)

Buy
One of the most basic laws of a web application is that the client, not the server, must initiate any communication between the two. There are a number of common–use cases where, ideally, the server would like to talk to the client—dashboards and monitoring apps, chat rooms and other collaborations, and progress reports on long–running processes. Comet (a.k.a. Reverse Ajax) provides a mechanism for enabling this. Comet is moderately complex to implement. But this practical, hands–on book gets you going.
  • In Part 1 of this book, we start by examining the use cases, and look at the simple alternatives to Comet and how far they can satisfy your needs. In some situations, though, only Comet will do.
  • In Part 2, we demonstrate how to set up and run a Comet–based application.

With this book, be a part of the next generation, Ajax 2.0.

What you’ll learn

  • Find out what Comet is and the trouble with HTTP.
  • See how to achieve push, polling, piggy–backing, raw sockets, and more.
  • Explore some common use cases and a worked example on “magnetic poetry.”
  • Understand what some issues and techniques are including the two–request limit, pub–sub and server architectures, and continuations vs. native Comet.
  • Use implementations of Comet, including Cometd/Bayeaux, Reverse Ajax in DWR, and more.
  • Work through the final example using DWR Framework.

Who is this book for?

This firstPress title is for Ajax developers who are intrigued by Comet/Reverse Ajax, key to the next generation Ajax 2.0.
