The last paragrpah of 14.9.4 says:
The proxy-revalidate directive has the same meaning as the
must-revalidate directive, except that it does not apply to user-agent
caches.
It should be changed to:
The proxy-revalidate directive has the same meaning as the
must-revalidate directive, except that it does not apply to non-shared
user-agent caches. It can be used on a response to an authenticated
request to permit the user's cache to store and later return the
response without needing to revalidate it (since it has already been
authenticated once by that user) , while still requiring proxies that
service many users to revalidate each time (in order to make sure that
each user has been authenticated). Note that such authenticated
responses also need the Cache-Control: public directive in order to
allow them to be cached at all.
in order to explain the motivation for the directive.
