 Argggh!

 21:59 < phk> With respect to deflate, you need to have ESI in mind while
 doing that, as you will be using the same object duplicity/selection
 stuff.

 21:59 < phk> You should also put the "Vary:" header on the 1.1 list, it's
 necessary for Deflate.

 21:59 < EvilDES> phk: deflate can be done orthogonally by hashing on Vary
 headers in addition to Host + URL

 21:59 < phk> no, that's the wrong way.

 22:00 < phk> we only hash URL+HOST

 22:00 < phk> the hashheader you get then has a list of objects for that
 combination.

 22:00 < phk> these objects can differ in TTL, encoding, transfer encoding
 or anything else you care to think about.

 22:00 < EvilDES> OK.

 22:00 < phk> and as you walk the list, you find one you like, or you
 create a new

 22:01 < phk> and get it from the backend.

 22:01 < phk> There is no way to sanely hash the vary header as it is
 defined.
