How does a server push content to a browser -- or rather, how does it appear to do such?
For example, consider a chat room application (like http://phpopenchat.org/features.php), where the text from users appears on the screen as users enter it in. All, without an annoying flash of a meta-refresh tag, or a page reloading or anything. Are they using javascript on a timer to poll the server to get the info and post it? Anybody ever done this?
