This is a Very Bad Idea, but your problem happens regardless of what you
configure so I will skip that for now...

Because "Vary:Cookie" the object returned for that URL changes depending
on content encoded inside the Cookie headers.

Cookie is so large and changes so easily that there are nearly an
infinite number of objects cached for that one URL. HIT'ing on a
previously cached copy is highly unlikely.
