I could live with either of these options; #1 is what the proxies
currently use; #2 would impose more requirements to server software,
but may yield a better uniform environment where the cache-control

True -- but the number is still pretty large (if this is continuing
the discussion of whether it's 50% or 90% hit ratio that we should be
targetting at).  Even if all of the HTML in the world became dynamic
and couldn't be cached, 75% of URLs, and far more than that measured
in bytes could be cached (images are still cacheable, and image files
are in average larger than HTML).  [Numbers quickly pulled from
Netscape's site cache and not accurate.]
