The state of many web applications is inherently volatile. Changes can come from numerous sources, such as other users, external news and data, results of complex calculations, triggers based on the current time and date.
Stream server data in the response of a long-lived HTTP connection. "Page Streaming" involves streaming the original page response.

All of a sudden, one of the machine displays goes red, indicating overload, and Frank heads over to investigate. How can the application keep users informed of changes occurring on the server? The state of many web applications is inherently volatile. The browser periodically issues an XMLHttpRequest Call to gain new information, e.g. one call every five seconds.
