nginx 1.9.12 proxy_cache always returns MISS

[shiz]

Yes it's resolved.

I've change the cache path yesterday and a few minutes ago, I noticed that
error message:

"2016/03/19 12:31:02 [emerg] 8984#8984: cache "my_zone" uses the
"/tmp/nginx/dev" cache path while previously it used the "/tmp/nginx" cache
path"

It seems it was enough to prevent the cache from running.  Interesting.

BTW, do you see anything useless, redundant in my config?

Thanks for the help!
