Suggestion: Don't Delete Cookies
Deleting the temporary Internet files is a good thing but deleting cookies is a bit extreme as they can do 'good' things like remembering that you've already logged onto AS so you don't have to log in again. I keep mine tidy with Ad-aware but never delete them as doing so means I have to remember passwords and re-log into sites I use regularly.
Obviously if you view 'dodgy' material which you pay for with a credit card then do keep these files as empty as possible as the Police will be knocking on your door with a heavy hammer very soon but remember that a techy person can even view deleted files...
I'd also suggest that the Refresh button doesn't just bring up a page from cache (temporary storage) but does actually get the page re-downloaded from the server as opposed to the back button which gets it from cache... [F5 = Refresh in IE!]
