Fwd: New Version Notification for draft-ietf-httpbis-key-01.txt

[Mark Nottingham <[e-mail]>]

I've done a quick editors' draft to try to move forward on a few of the issues.

Note the issues proposed to be closed in this round:

* Support "Or" operator <https://github.com/httpwg/http-extensions/issues/104>
* Policy for Key parameter registry <https://github.com/httpwg/http-extensions/issues/106>
* Whitespace requirement <https://github.com/httpwg/http-extensions/issues/107>
* field-name cardinality <https://github.com/httpwg/http-extensions/issues/108>

If you have concerns about those resolutions, please bring them up here or the issues list.

If that sticks, I'd note that we only have two open issues:

* Case Handling <https://github.com/httpwg/http-extensions/issues/105>
* Generational Constant <https://github.com/httpwg/http-extensions/issues/109>

WRT #105, I'd love to hear what people think about the options here. It seems to me that we could do any of:

* Leaving it as is
* Making some subset (or all) case-insensitive
* Introduce a flag for case insensitivity (at the potential cost of complexity).

WRT #109, I think we need to see a detailed proposal before we can make progress. 

I think we're also getting close to the time when we really need some implementation experience. Anyone? 

Cheers,

> Abstract:
>   The 'Key' header field for HTTP responses allows an origin server to
>   describe the secondary cache key (RFC 7234, Section 4.1) for a
>   resource, by conveying what is effectively a short algorithm that can
>   be used upon later requests to determine if a stored response is
>   reusable for a given request.
> 
>   Key has the advantage of avoiding an additional round trip for
>   validation whenever a new request differs slightly, but not
>   significantly, from prior requests.
> 
>   Key also informs user agents of the request characteristics that
>   might result in different content, which can be useful if the user
>   agent is not sending request header fields in order to reduce the
>   risk of fingerprinting.
