ISSUE-28: Align content type rules in HTML 5 with IETF specs for HTTP and content-type sniffing
http-mime-override
Align content type rules in HTML 5 with IETF specs for HTTP and content-type sniffing
- State:
- CLOSED
- Product:
- HTML Principles/Requirements
- Raised by:
- Dan Connolly
- Opened on:
- 2008-01-23
- Description:
- The HTTP specification, in section 14.17 Content-Type, says The Content-Type entity-header field indicates the media type of the entity-body sent to the recipient.
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17
The HTML 5 specification specifies an algorithm for determining content types based on widely deployed practices and software.
http://www.w3.org/html/wg/html5/#content-type-sniffing
To the extent these specifications overlap, the IETF HTTP Working Group has a right of review.

Related notes:
The design seems somewhat stable within the HTML WG... haven't seen much new information lately... main concern at this point is coordination with IETF HTTP WG, TAG, etc.

hmm... I wonder how this got closed; I don't remember any sort of "any objections?" message/poll. I think I would have objected to the current editor's draft.
not sure how/why this got closed; changing back to RAISED

13 Aug 2009, 15:52:27"If referencing an unstable external spec is an issue, we can raise that separately."
seems like unnecessary churning. This "issue" has all the history, and moving the specs around in the IETF don't warrent closing one issue and raising another.
