Caching has nothing to do with the back button. You can tell it not to cache 
in any way you want but a properly written browser will ignore all of that 
for the back button. The back button is supposed to bring back whatever was 
on that page when it hit it just recently. Just like undo/redo operations. If 
your app design is based on hitting back and having the page refresh then 
your app design is broken and will not truly work. You might be able to put 
some hacks on a page with javascript that might cause it to reload but I 
don't know how you would really do it. 

Nothing about zope changes this since it is how browsers are supposed to work. 
Either make the app work when people hit the back button or tell them that 
using that will break things on the site and provide other ways to navigate 
so that the back button never needs to be pressed.
