I've never noticed browsers paying any attention to Expires.  Browsers
seem to either use If-Modified-Since, or assume that since they
downloaded it five minutes ago, it must still be valid.

Cache-Control is a HTTP 1.1 thing.  No way will it work with older

Otoh, Pragma: no-cache always seemed to work with older browsers, when
older browsers was all we had.  Whether it works with newer browsers, I
don't know.
