Re: No-Vary-Search

Hi David,

Well the nice thing is that if you choose a generic name for the header
(i.e. not including 'search'), then even if it *initially* only applies to
query params, if at some point in the future we want to also allow it to
include other things (thumb-in-the-air example: shared caching across
subdomains like "www" and "api" and the TLD) then you don't need to create
an entirely new header - you just add new allowed values to this header.
