The web has evolved from a document repository into a multi-user collaboration medium, shaped and created by its users. Ajax Push gives the server the ability to update any part of any page at any time, transforming every application into a new communication tool, connecting users to each other through web server mediated channels. In this session, recorded at the recent JSFOne conference, Ted Goddard provides an overview of Ajax Push and its range of uses in multi-user web applications. By stepping through the development of a multi-user slideshow and chat system, he shows you how easily sophisticated Ajax applications can be created.
