Maybe you could set up your logout page as an intermediate page which does 
the logging out (clear session, expire cookies) then does a cflocation to 
the login page.  This intermediate page wouldn't display anything.  Then if 
the user clicks the back button, they go back to the intermediate logout 
page and are cflocation'd to the login page again.
