Could anyone recommend any tools to be able to see where external files / images are being loaded from. By this I mean that I’m aware that external JS files / Images are cached on the first load of a page. What I’d like to have is a tool that confirms to me that on subsequent requests these files are in fact being loaded from the users cache rather than downloading the file again.
Apologies, if this has been answered elsewhere, I have tried search but with no luck.
Thanks
David
If you are using firefox as the browser, I find that Firebug is a very useful resource for helping with those things, and many others.
