Reverse AJAX?

This is not something new and GMAIL users would already have experienced it while keeping the browser window open for long time and reciving new mails. These guys have named this technology as Reverse Ajax.

This is not something new. You could make something similar by calling your AJAX method after regular interval by using setTimeout() method of javascript but the features DWR provides are given below:

 

Polling
At regular and frequent intervals, the browser sends requests to the server to see if the page has been updated.
Comet
After a request has been received from the browser, the server keeps the reply open so that it can pass down information when it arrives. This is also known as a long-lived HTTP connection.
Piggyback
When the server has an update to send, it waits for the browser to make a request and then sends the update in addition to the requested information.

 

 Since it's available in form of Java Library then definately would save lots of time to produce similar results while working on AJAX applications. I would try my best to use it in some application to test its strength.


 

 People are also talking about it on AJAXIAN
