Here was my experiment: (1) Create a minimal page with the onbeforeunload event and a link. (2) Visit that page in your browser. (3) Edit the page on the server by inserting a word or something. (4) Click on the link (5) Press the browser's "back" button. In both IE7 and FF2 it goes back to the original version, i.e. its old cached version, the one without the inserted word.
