Nginx caching... but shouldn't be.

[dgarstang]

We have nginx running, and for reasons I don't understand, it seems to
be caching content to /var/lib/nginx/proxy. I can't even find this
setting in the configuration anywhere, i.e. the following returns
nothing:

root at lb01:/etc/nginx# find /etc/nginx | xargs grep "/var/lib/nginx"

We have the following set:
    proxy_no_cache 1;
    proxy_cache_bypass 1;

I have pasted our config to http://pastebin.com/w7E0trG6. If anyone has
any ideas why nginx is caching, it would be appreciated.

Doug.
