I definitely see your point -- as I see it we're talking about a
"lesser of evils" situation. When you "back up" to an expired page,
there are only three things I can think of that could happen:
1. you see the expired document.
2. you see an error message and (if you interpret the message correctly)
you can reload the page manually
3. the browser reloads the page behind your back.

Well, as Lori Anderson would put it, "?Que es mas macho?"
I guess I'd pick door number 1 -- but only for the case where you view
the page with browser navigation commands, not explicit links.
