Having read both
http://www.ics.uci.edu/pub/ietf/http/draft-mogul-http-revalidate-01.txt, and
the diff version of rev-03, I am now confused about the Cache-control
revalidation directives, and their intended interaction with the Authorization

The text in 14.8 appears to allow me, as a proxy, to serve objects requiring
authorization, without first validating the user's credentials, as long as the
object is fresh.

14.9.4 seems to say that must-revalidate is not unconditional, but rather that
it only requires revalidation if the object is stale.
It further seems to say that proxy-revalidate can be used to require shared
proxies to authenticate each user.

So, an origin server should send both "proxy-revalidate" and "public" to force
If so, I think at the very least this should be added to the list in 14.8, and
that proxies ought to be required to revalidate in this case.
If not, I need educating.

Thank You,
Richard L. Gray
