Re: Draft TAG finding available: Client handling of MIME headers

Ian,

	Following Julian Reschke comment, I would like to suggest that
the document explicitly states that MIME headers are emitted by both
clients and servers. Alternatively, the document can explicitly define
"server" as "content provider", but that is probably an overkill in
this case.

	We have seen many cases where HTTP implementations assume
unidirectional nature of content flow (the server sends content at
client's request but not the other way around). The result is a loss
of interoperability and even security vulnerabilities when the content
starts flowing in the other direction. A prime example is handling of
chunked requests by HTTP servers; many implementations forget about
their existence or mishandle them (while generating valid chunked
responses).

	The "mime-respect" document is probably the wrong place to
document the general problem, but it can emphasize the MIME-specific
aspect of it, perhaps while answering Julian's questions.

HTH,

Alex.
