Just a question.  Are you specifically using cookies or are you talking
about session cookies?  If you aren't using sessions themselves, I would
suggest you move in that direction and only use cookies for keeping a user
logged in.

Second thought for the cookies, you could make a tweak to your cookie value
that contains some sort of flag and if a user doesn't have that flag, it
will clear their cookie and redirect them to the login page.  A second
cookie could do the same thing.  That way, only those with this flag or
even a certain value in that flag will still work.  Others will be logged
out and this would "automagically" reset their cookies.
