Henry, My only concern with [2] is this set of requirements > Such recipients SHOULD NOT override the specified type it there are > known security risks and they SHOULD provide for users to disable such > heuristic Content-Type detection. as discussed before. HTTPbis can introduce new requirements that break existing implementations only where there are overriding security and/or interoperability concerns. While it could be argued that this holds true here, the first requirement is quite vague, and the second will AFAIK make every existing implementation non-conformant (with the possibility that they will remain so indefinitely). Would the TAG be amenable to either dropping this sentence from the proposal, or modifying the text at [3] to address your concerns? Regards, On 09/06/2010, at 10:47 PM, Henry S.
