This paragraph points up an important distinction which
I think has been part of the problem with the discussion
of 303s.  They can be looked at in two different ways:

1. Small speed bumps on the way to a 200 response, which
set a flag that the eventual response is somehow not
quite really a representation of the resource you
originally asked for, or

2. Pretty much the same as a 404, but with a consolation
prize in the form of a hint as to where to go to look
for more information.

It seems to me that a lot of the discussion has been
people coming from these two viewpoints talking past
each other.

The actual protocol on the wire is the same in each
of case, it's how you think about what's happened that's
different.  Hence, the specs, RFC 2616 in particular,
are not so helpful.

I'm in the second group - but only because it seems like
the right design to me, not because the 2007-05-31/
HttpRange-14 draft or RFC 2616 makes it the only
reasonable interpretation.  In  fact, the wording of
RFC 2616 seems to lean more towards the first viewpoint
but, perhaps, only because it was originally written
with the response to a POST in mind which is not
applicable here.
