Date case sensitivity

[mnot]

Caching 4.2:

Although all date formats are specified to be case-sensitive, a cache recipient should match day, week, and time-zone names case-insensitively.

What does "week" refer to in this text? Also, why is this separate from the text on HTTP-dates? Do we really mean that caches should parse them in a different fashion than other components?

...we probably should find out when and why this difference was introduced...

[bagder]

Is "week" perhaps meant to be "month"?

[mnot]

This appears to have been added in 7234. The obvious thing to do is to use the appropriate rule names from semantics: day-name, day-name1, month and GMT.

The relevant tests seem to support this.

It also probably makes sense to mention this relaxation in Semantics, seeing as how caches are one of the primary consumers of dates in HTTP.

Ok, after some digging I found: https://trac.ietf.org/trac/httpbis/ticket/165.

(so it was me :-)
