As you say in your conclusion, "most of our criticisms are related to
weaknesses in the specification, not in the design itself".

You make 15 recommendations for the HTTP/1.1 specification.  I think
we should discuss each of them. Many of them are of a 'clarify'
nature, and we should certainly clarify the specification if it is
actually ambiguous. Some of your recommendations are in the form of
implementation suggestions which, while important, might not be
appropriate for the HTTP/1.1 specification itself. There are a only a
few recommendations that actually look like protocol changes, and in
some cases, may be based on a misunderstanding of the spec rather than
something that is incorrectly specified.

In any case, your careful analysis and sample code are quite useful.
