[ale] Page Expiration

[kevinostoll at yahoo.com (Kevin O'Neill Stoll)]

If a user clicks the back button in a browser I need for
the previous page to come up expired. I have noticed that
some financial institutions do this, such as Wachovia or
BOA. 

I have done some research on how to do this but maybe I'm
just looking for the wrong thing. I haven't found what I
think I'm looking for.

Thanks for the help.
