COMET - The Next AJAX
Digital Web Magazine - News - Comet, the complement of AJAX
AJAX allows a browser to, at any time, communicate with the server and deliver the results of that communication to the browser without the need for a page refresh. COMET promises the same use of existing technologies to allow the server to push information to the browser without the need for a browser request. The ability for web pages to both send and receive data, initiated by either the server or the client, without a browser refresh will really transform the deliverable experience.
