That's what the Expires header is good for, isn't it? See
<http://www.nads.de/NADS/Ueberblick/heute> for an example. This URL
gives you an overview of events in D|sseldorf and about for the
very day. It expires at the end of the day (local time in Germany).
(In fact, it is just a 302 Redirect message pointing to the real
document. To make the CERN httpd cache redirections, see my patch
under
<http://www.nads.de/NADS/Public/WWWTechnik/WWWDaemon-patch.01.gz>.)
