I would propose to also reduce the MUST NOT restriction in 14.7 down to
a SHOULD NOT which is more appropriate for this kind of restriction. Or
drop it entirely from there.

There is many scenarios where the proxy may actually know by
administrative policies outside the protocol that the user agent does
not have any other means of communication, so the assumption made in
14.7 is not necessarily true. MUST level requirements based on false
assumptions isn't that great.. Also, it does not make much sense to me
having this MUST requirement on non-transparent proxies.

So I propose the following

14.7

      A proxy MUST NOT modify the Allow header field even if it does not

changed to

      A proxy SHOULD NOT modify the Allow header field even if it does not



plus the already proposed 

13.5.2

"Allow" added to the first list of unmodifiable headers "A transparent
proxy MUST NOT modify"..




If 14.7 is kept as a MUST requirement then the directive needs to be
added in a new MUST section in 13.5.2 stricter than any of the existing
sections.

Henrik
