Is this a better scheme to use than "Expires" ?

Some lazy (ask first, try later) questions..

Does it suffer from the Netscape-brain-damage where after the
age has been reached, Netscape will keep requesting via "get-if-modified"
and never update its cache settings ? (netscape goes into an infinite
loop with animated gifs here).

Will the header always be applied, even if, say a "not modified" response
has been returned ? "Expires" headers have to be sent each time and
I suspect "Cache-Control" would be the same.

Sounds like it might be worth a try.
