Ok, I *really* don't want to open this up again full-blown, but I just
have to ask ...

Wouldn't the prior knowledge of HTTP application semantics by an HTTP
intermediary qualify?  I would agree that, for example, an SMTP message
isn't visible to an HTTP intermediary.  But there's shared knowledge
on application semantics in the HTTP/HTTP case.

I'm not trying to conclude the previous thread.  Just hoping that we can
find agreement on *some* degree of loss in visibility with the method
in the body.
