    It used to be AJAX, then there is now Comet. Just then, there is also HTML5 Web Sockets.

    But i guess what is prevalent to your situation at present may be solved by Comet.

    Its called pushed notification.

    AJAX can be used in a pull notification manner, i.e. browser periodically checks the server for updates. Comet is for push notification, i.e. server sends updates to the browser.

    Web Sockets is only relevant in HTML 5 enabled browsers.
