I'm truly embarrased to ask this question, but other avenues have not 
provided a solution. I don't know if the problem is in my HTML, the 
browser configuration, or Apache.

I have a very basic web form that takes in some values that are used in 
a subsequent database query. After submitting, if the user elects to 
back up in the browser cache in order to make a few changes on original 
form and then re-submit, he/she finds that the entire form has been 
reset. This only happens with MSIE (version 6.0.28) on Windows XP. When 
I use Safari on MacOSX, the form retains the previously entered values 
when I back up to it in the browser cache. (Of course, forms on *other* 
web pages retain their values, even with MSIE on Windows).

I tried setting an "Expires:" header on the page containing the form 
using the header() function, but this had no impact.

I thought it was usually the case that people have trouble 
*eliminating* caching!

Server Specs:
MacOS 10.3.8
built-in Apache 1.3.29
PHP 4.3.4
MySQL 4.1.3-beta
