Added additional acceptance test for variant negotiation: 

"If any of the existing cache entries contains only partial content
for the associated entity, its entity-tag SHOULD NOT be included in
the If-None-Match header field unless the request is for a range
that would be fully satisfied by that entry." 
(http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.6)
