c# - AJAX progress bar dispaying loading progress percentage for page load

Question

How do you use a progressbar to show the loading percentage for a page? ...(similar to how they show in flash)

Thanks

Impossible(on IE8 & FF3 & Opera without plugin or extension). If you want real loading percentage include HTML + Javascript + Stylesheet + Image. you can only detect how many file loaded to page(only Image & javascript can be detected by this technique).
