While I don't think this (above) is practical as images, etc, cannot be
given such a warning, maybe the error page should have a link to something

titled, say, "An old cached copy is avaliable".

And squid could be made to return and data from neighbours or itself which
it can find, regardless of expiry dates, for these special requests?

Would this be able to be implemented?
