Mmmhhh, do you think I should remove these and trust nginx's default values
for these buffer?

Ok, I changed that to:
proxy_cache_key "$scheme$host$request_uri";

I also made few additions under location/:

    proxy_cache_valid 200 302 304 10m;
    proxy_cache_valid 301 1h;
    proxy_cache_valid any 1m;

    proxy_next_upstream error timeout invalid_header http_500 http_502
http_503 http_504 http_404;

Do you think these are good and justified?

Unfortunately I'm seeing these warnings now:
"an upstream response is buffered to a temporary file"

Any hints why? Help is much appreciated
