I’m looking for an easy way to tell if a web browser downloaded a web page element (image, CSS, JavaScript, etc.), or if it got a positive cache hit and pulled it from there. Does anyone know of plugin for Firefox, Internet Explorer, Safari or Opera that will do this?
Here’s an example of what I’d like to do. Flush the browser cache, load a page. There should be zero cache hits on the first page load because I just flushed it all. Then load the page again, after which I’d get a list of object in the page that were pulled from cache and those that weren’t.
Any change Firebug 1.0 will have this feature?
