You cannot use meta *elements* to control caches (except possibly the
one in the browser) as caches are HTTP devices and do not need to understand
HTML at all; you must use real HTTP headers.  I believe this whole use
of such elements is controversial and an after the fact standardisation
of de facto practice.

Real HTTP headers, in conjunction with an HTTP 1.1 proxy, allow this level
of control.  Please read the RFC.

Please don't do this on public lists.
