ISSUE-28

http-mime-override

Content type rules in HTML 5 overlaps with the HTTP specification?

State:

PENDING REVIEW

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.
