How to Nginx cache server setting

Thu Feb 27 15:47:43 UTC 2014

Hi everyone

I would like to make reverse proxy and cache server from Nginx using CentOS6.5,
The setup of Nginx is as follows. 

But, cache information is not saved in /var/cache/nginx/hoge.com of proxy_cache_path.
Is this because a setup is wrong? 

Please advise me.
