i37: Vary and non-existant headers


Roy sort-of proposed deleting "present" in <http://lists.w3.org/Archives/Public/ietf-http-wg/2006OctDec/0090.html 

In addition, I'd propose:

* adding: "When a resource's representations vary, an origin server  
SHOULD include the Vary header even when the selecting header(s) are  
not present; otherwise, caches will use that representation  

* adding: "Caches MAY canonicalise request headers before comparing  
them for purposes of determining whether they match during variant
