 * I understand this is only for automatically emptying the cache, can you please
   add a link on how to set up a cache?
    what type of cache is this emptying? What
   is being cached anyway?
 * I just moved to a new VPS server using nginx + PHP-fastcgi
 * no caching set up yet, except for using the w3 total cache plugin.
 * haven’t set any expires headers either, still reading up on that matter.

 * Hi Ovidiu and thanks for your interest in our plugin.
 * You can find a Nginx Configuration example in the Overview submenu page in Nginx
   Manager plugin page.
 * Hope this helps.

 * ah, I see. I should be fine with those examples, except I am not sure what these
   lines are supposed to be/mean/do:
 * `proxy_pass http://ALL_backend;``
 * and
 * `proxy_pass http://ALL_ADMIN_backend;`
 * what do I replace ALL_backend with? are those variables?

 * oh and did Iread this right that all I need to replace in that example are:
 * – YOUR_CACHE_NAME
    – /path/to/cache/your_cache
 * and maybe the caching times/duration, I mean the rest are just set variables,
   right?

 * `proxy_pass http://ALL_backend;`
 * ALL_backend and ALL_ADMIN_backend are two variable that contains the addresses
   of all the backend and admin backend server.
 * In our configuration we have something like
 *     ```
       upstream ALL_backend  {
         server 111.2.3.1:80;
         server 111.2.3.2:80;
         server 111.2.3.3:80;
         ...
         server 127.0.0.1:8080 backup;
       }
       ```
   
 *     ```
       upstream ALL_ADMIN_backend  {
         server 111.2.4.1:80;
         server 111.2.4.2:80;
         ...
         server 127.0.0.1:8080 backup;
       }
       ```
   
 * About the things to change: the other values are about the cache duration etc.
   It’s better you read NGINX wiki for details.
 * ciao

 * thanks for all that info, but I am wondering why the Nginx Configuration example
   in the Overview submenu page in Nginx Manager plugin page doesn’t even mention
   the need to set up the backends as Hpatoio explained. I think that is valuable
   information.
 * Btw. is there a specific need to have a separate proxy for ALL_backend and ALL_ADMIN_backend?
