This draft does not discuss the Content-* rule. Content-* headers are special, in that they may not be ignored (section 9.6 of [RFC2616]). Recipients not understanding Content-blah: will generate a "501 (Not Implemented)" error code. That overrides the proposal below, I think. The proposal in the draft doesn't appear to work with proxies, which often may be passing through headers that they themselves don't understand. This draft does not appear to be associated with a working group. I suggest discussing this on the hybi mailing list; it's a little offtopic, but a bunch of http experts do read that list and can offer comments. -----Original Message----- From: ietf-announce-bounces@xxxxxxxx [mailto:ietf-announce-bounces@xxxxxxxx] On Behalf Of The IESG Sent: 13 December 2010 13:28 To: IETF-Announce Subject: Last Call: <draft-yevstifeyev-http-headers-not-recognized-08.txt> ('Headers-Not-Recognized' HTTP Header Field) to Experimental RFC The IESG has received a request from an individual submitter to consider the following document: - ''Headers-Not-Recognized' HTTP Header Field' <draft-yevstifeyev-http-headers-not-recognized-08.txt> as an Experimental RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action.
