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.
