I actually have the log out stuff with no back in it (thanks to some folks
on this list)- it's the regular pages that I need to refresh. So here's the
code on my log out page. There's no one way to do it-it depends on the
browser/machine/etc. I had a horrible time finding something that would work
on the Mac!
good luck,

I have never been able to get the Meta Expire to work correctly. Is
there a cross browser solution to successfully expire the page cache so
you can't hit the back button and return to already rendered pages? I
especially wanted to use this to clear the cache after people logout of
the application. I'm sure someone has spent the time needed to figure
this out.

You could try this:
<cfheader name="EXPIRES" value="#NOW()#">
