Meta-tags are no good. Httpd itself can send an Expires: header, the same as it
does for Date:, Server:, Content-type:, Content-length: etc etc. You don't want
Squid parsing EVERY document that it fetches (which also applies to PICS).

Even the NLANR web site doesn't send out Expires: headers. Apache is able to do
this plus Apache are planning to release a fully compliant HTTP 1.1 server as
close to HTTP 1.1 becoming a standard as possible (give or take last minute
code changes due to last minute changes to the proposed standard, see
