One combination of headers which is a bit hard to track should also be
considered (I hope I didn't just miss this issue):

|Content-Language: de
|Vary: accept-language

New apache servers (and possibly others) can send documents modified for
different languages a user wishes to accept. So a request for http://foo/
might give a different page for every hit. Last modified gives in this case
the "real" last modification date not when the server decided to server what

One approach to cache these pages would be to introduce some "meta-URL"
mode://[;language] for internal use. So if you get a
request for the english version of http://foo/ then you first look (in cache)
if http://foo/ is present. Then if not look for http://foo/;en and so
on for the content of the "accept-language" header.

Is perhaps a bit harder to code, but these pages that will vary on
Accept-Language will become more and more.
