Evolving profligate and conspicuous web applications using reverse AJAX

Web based application are generally based on request - response model. AJAX is a technology where the client sends the request and the server sends the updates (response) to the client without a full page refresh. It is still a request-response model, where there is Asynchronous interaction to obtain the data asynchronously from the server by raising a request for every data required. Recent developments in AJAX have led to a new dimension called as Reverse AJAX also called as AJAX2.0 where the server sends response to the client only when there is an update in the server. This paper describes the basic concepts of Reverse AJAX, how those can concepts can be utilized and is backed up by presenting an implementation of a chat room application using Reverse AJAX.
