A properly functioning cache should not be serving a document whose
original has been updated. In practice, depending on the guesswork
and arcane magic used to conjure up expiry dates, I suppose current caches
will serve them, so Martijn's concern is well placed.
BTW wasn't the point of LINK REV=made href="mailto:blah@site" so that
clients could notify the maker of a document if it had broken links?
I thought some browsers already did this - Lynx springs to mind.
