Since 0.8.44 nginx doesn't cache by default responses with 
Set-Cookie.  If you want them to be cached you have to add 
"proxy_ignore_headers Set-Cookie".

Note well: you may also want to add "proxy_hide_header Set-Cookie" 
(or make sure cookies set aren't private, or make sure your 
proxy_cache_key distinct for different users).
