Meta tags are not parsed by servers - only the browser uses them.
At the moment, Squid works best if servers use Expires: headers.[*]
You could also usefully configure things so that a default expires
is a percentage of the LM time - this isn't the default configuration.

-- jrg.
(* there is a module for Apache, I believe, that allows one to use
CERN's meta type files and send extra headers; or you could use an
as-is Apache file type to send an entire file, headers and all, verbatim.)
