#449 closed editorial (incorporated)

Receiving a higher minor HTTP version number

Reported by: mnot@… Owned by: draft-ietf-httpbis-p1-messaging@…
Priority: normal Milestone: 23
Component: p1-messaging Severity: In WG Last Call
Keywords: Cc:


I don't see anything in p1 2.6 Protocol Versioning that explicitly says an implementation ought to accept a message that has the same major version number it implements, but a higher minor version number.

I think we need to spell this out, because IME some servers do error out on (for example) a HTTP/1.2 request.

Also, it might also help to add "major" to the first sentence of the description of 505 in p2:

The 505 (HTTP Version Not Supported) status code indicates that the server does not support, or refuses to support, the protocol version that was used in the request message.

Because some people will read that and stop.

From [2277]:

Clarify that a recipient SHOULD process received messages in higher minor versions as if they were the highest minor version to wwhich the recipient is conformant; Clarify that 505 is for major version rejection; addresses #449
