Ok, you have written a nifty application with an embedded SWF object. Now you would like to make the SWF object to reload itself because you know that meanwhile the Flash movie on the server has changed. You would dynamically rewrite the <div> ID block containing the SWF object using the same URL (because the server and the movie actually remains the same, only the contents has changed).
