Cache permissions problem

[hpatoio]

Hello. 

I've a custom build of nginx (1.4.6) with ngx_cache_purge module (2.1)

In the config file I've a cache zone declared like this: 
  proxy_cache_path /tmp/nginx_cache keys_zone=MYCACHE:10m;
I don't have specified any "user" (http://wiki.nginx.org/CoreModule#user) in
my config.
When I run nginx with my user the cache directory is create with permissions
drwx------ and is owned by my user and my group

The problem is that nothing is written in the cache directory. If I run
nginx with sudo everything works.

Where am I wrong ? Hints ?

Thanks
