Other than periodically refreshing the page, you have two options:
1. Using AJAX to continuously poll the server;
2. The "multipart/x-mixed-replace" MIME type;
3. Server-sent events <http://labs.opera.com/news/2006/09/01>.
A page refresh will offer the widest range of browser support. AJAX will
work in any reasonably modern browser with Javascript enabled. Multipart/
X-Mixed-Replace is an old Netscape 1.x push technology, which is still
supported in Gecko-based browsers, plus Opera and Safari, but not Internet
Explorer. Server-sent events, although the neatest solution are only
supported by one browser so far -- Opera 9.x -- expect wider browser
support in the future.
