Yes, but why would you ever _want_ that to happen on your site? If a visitor
sees a stupid browser message while on my site, then I'm not earning my
paycheck. Instead, I use the no-cache feature of PHPLib's sessions to
rebuild the page. Of course some browsers, like Opera, may cache the pages
anyway (and I think Opera is right to keep a true history of pages seen).
Any problems caused by actions taken from an obsolete page will be caught by
basic data checking.
