I vaguely recollect that you have a reason for forcing reloads on movements in the history list; but I hope you do realize that, in general, unasked for re-requesting due to movements in the history is a major pain in the neck. It's something that I (as a server author) have had to try and "break" (by adding expires of a several minutes to otherwise static documents). Not something I'm proud of, but better then the all too frequent behavior of most versions of netscape that I've used.
