Comet and Ajax

04 Sep 2007

Tagged with Miscellaneous

Comet is a pro­gram­ming tech­nique that enables web servers to send data to the client with­out hav­ing any need for the client to request it. This tech­nique will pro­duce more respon­sive appli­ca­tions than clas­sic AJAX. In clas­sic AJAX appli­ca­tions, web browser (client) can­not be noti­fied in real time that the server data model has changed. The user must cre­ate a request (for exam­ple by click­ing on a link) or a peri­odic AJAX request must hap­pen in order to get new data from the server.
