The pushes page updates to groups of pages. ICEpush handles all aspects of the asynchronous blocking connections involved, including connection management/sharing, heartbeating, and ARP integration.Ījax Push can be added to an application with just two lines of code. The diagram shows a single client recipient of a push, but the mechanism supports named groups of clients that all receive notifications.

Render phase captures new state of client, and Direct-to-DOM Rendering delivers incremental page updates to client.

Notification at client browser causes a JSF Ajax request with an empty execute phase.

ICEpush notification is delivered to the browser client over a dedicated ICEpush connection.

Some state change in the application triggers an Ajax Push event.

The sequence of events involved in Ajax Push is illustrated below. Simply put, ICEpush uses long polling to provide asynchronous notification over standard HTTP, using only standard browser capabilities. Ajax Push in ICEfaces leverages an asynchronous notification mechanism called ICEpush. It is, however, useful to understand the basic mechanics.

The intricacies of the Ajax Push implementation are completely transparent to the ICEfaces developer, as you work with a straightforward set of APIs. Ajax Push is the key to building collaborative, multi-user applications for the web. This is a small change in terms of the technical capabilities of Ajax applications, but it is a revolutionary change in terms of what applications can actually provide to users.

Ajax Push allows the application to incrementally update any part of the page at any time, for any group of clients.
