The following errata report has been rejected for RFC6265, "HTTP State Management Mechanism". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=6265&eid=3765 -------------------------------------- Status: Rejected Type: Technical Reported by: Johannes Knaupp <info@firmen.jknaupp.de> Date Reported: 2013-10-25 Rejected by: Barry Leiba (IESG) Section: 4.1.1 Original Text ------------- Servers SHOULD NOT include more than one Set-Cookie header field in the same response with the same cookie-name. (See Section 5.2 for how user agents handle this case.) Corrected Text -------------- Servers MUST NOT include more than one Set-Cookie header field in the same response. Notes ----- The HTTP specification (RFC 2616) says in its section 4.2: "Multiple message-header fields with the same field-name MAY be present in a message if and only if the entire field-value for that header field is defined as a comma-separated list [i.e., #(values)]. [...]" Since the mentioned condition is not fulfilled in the case of Set-Cookie headers, only one Set-Cookie header is permissible in an HTTP message. This also applies to the third example in section 3.1, even though it is not clearly specified there whether or not the two Set-Cookies originate from the same server response. On the internet many HTTP messages contain multiple Set-Cookie headers, and this seems to make sense in order to avoid additional roundtrips. This, however, (1) does not match the HTTP specification, see above, and therefore (2) cannot be used with implementations stating that they were HTTP compatible and consequently only allow a single Set-Cookie header per response. Clearly, this is not a defect of those implementations, but of the specifications which are at least mistakable (if not contradictory). --VERIFIER NOTES-- Part of the point of RFC 6265 is to document how cookies are actually used on the Internet. As is noted in the introduction, existing use doesn't always conform to what it should. In particular, we know that RFC 6265 doesn't always match up with RFC 2616, because the actual usage isn't always strictly correct. The variation from RFC 2616 that this report notes is intentional, documenting the existing usage, and this errata report is rejected. -------------------------------------- RFC6265 (draft-ietf-httpstate-cookie-23) -------------------------------------- Title : HTTP State Management Mechanism Publication Date : April 2011 Author(s) : A.
