Is there NO ONE that can help with this error?

This is a repost... starting to feel invisible here... does no one know?

How do you get a web app to not show the 'page has expired...' error and
refresh and requery when you hit the back button after submitting a form? I
just want the old data to still be displayed in the form so the user can go
back, make a few changes, and submit again.

I checked knowledge base for this and I do not have "Do not save encrypted
pages to disk" checked and the user is running IE
6.0.2900.2180.xpsp_sp2_rtm.040803-2158 I am running server2003 and
IE 6.0.3790.0 update version 3283 and I don't have the problem.

thanks.
