But there is a problem... Proxies and caches...
AFAIK (took a look at spec too ;):
If, for example, in my corporation there are two guys, one using Windows in jp and one using Linux in en_US, if the first guy requests "http://www.vnunet.com/";, I'll deliver the page the first time in jp, encoded in shift_jis (let's not track content-type for a sec).
Vary: Content-Encoding
Now, when the second guy requests the same page, I'd have to send it in en_US maybe encoded in iso-8859-1...
Vary: Content-Encoding
But my corporation proxy (or the cocoon cache), will cache the first version it hits, so, to both of them, I'll end up serving the same Japanese shift_jis content...
Now, proxy will have 2 objects as it knows that responses were different.
Not good... Needs more thinking indeed...
:)
PS Worse case schenario is Vary: * which effectively disables any caching...
