The easiest way to cover your tracks would be to click the Safari menu and then click "Reset Safari". That clears all caches, history and form data.

interesting feature is also 'private browsing', where safari doesn't save any data from your browsing session. I was hoping Firefox had this too, especially when you surf another computer.
