Mark, this sounds like a great plugin. I especially like the fact that
it would deal with all the HTTP headers, since that's something I can
never keep straight.

Yeah, I've got a perfect candidate for this! I've got an embedded run
mode that displays a user-specific menu of documents. The menu is built
on every request, and I know it's not cheap to do so.

This looks very useful to me.

Or you could have a serial number that gets incremented whenever an
administrator makes changes. Then include the serial number in the
user's session and use that as one of the cache elements.
