http and html are prior art

Web browsers use header requests to determine if the page has changed before requesting the whole page again or displaying the cached local page. This is the same for widgets? The prior art is in http?

Does Apple mention programs? Widgets are scripts, not compiled executables, rather they are html documents. The widget should be updated if the header indicates a change...

Just a thought.
