There is a good summary here:
 http://www.pacificnet.net/~johnr/meta.html
Note the failure of IE4 to follow basic Pragma syntax (and their workarounds).
In my experience, IE4 and IE5 - under certain circumstances - still seem
to cache stuff at will.

Sorry for the newbie question but could anyone tell me how to expire pages
so a user can't use the back button to get back to that page?

Besides being a really bad idea, and next to impossible to implement, this
is not a mod_perl question, but a HTML/HTTP question. Once you've figured
those bits out you just need $r-header_out(), but its going to be much
harder than that.

use

my $headers = $r-headers_out;
$headers-{'Pragma'} = $headers-{'Cache-control'} = 'no-cache';
$r-no_cache(1);

Check this out:
