Where can I find $_SERVER[‘CC_NGINX_FASTCGI_CACHE_PATH’]?

This answer interest me too, because without this the plugin does not seem to work in my environment…

Hello @ateliershen and @draven666,

The requirements in the documentation weren’t properly defined. Therefor it was obviously unclear how this should be setup. The additional requirement is a Nginx server with fastcgi_cache enabled. In the Nginx configuration you should pass the CC_NGINX_FASTCGI_CACHE_PATH parameter to PHP with the proper path to the cache. In the tab installation you can find a link to the Nginx documentation where this functionality is described.

Keep in mind that the plugin in itself doesn’t provide any caching functionality. It only provides a way of clearing the fast-cgi and or pagespeed cache generated by an Nginx server as we have setup for our customers.

Kind regards,

Thank you @cacholong,
I have successfully configured the plugin and now it works ??

Let me share my process if anyone is not familiar with how to pass parameter to php from nginx:

1. nano /etc/nginx/sites-available/{your_conf_file}

2. Find location ~ \.php$ block, and add fastcgi_param CC_NGINX_FASTCGI_CACHE_PATH /your/fastcgi/cache/path; inside this block, remember to replace /your/fastcgi/cache/path with your path.

3. Save and exit. run nginx -t to test if the conf is correct.

4. service nginx reload . Now navigate to your WordPress, the cache should be purgeable.

Cheers,

Hello,

I use redis cache and this redis cache plugin: https://www.ads-software.com/plugins/wp-redis/

and also I am using Nginx helper to handle purge cache: https://www.ads-software.com/plugins/nginx-helper/

But I found “purge cache” does not work automatically, so two question here:

1. does it work with the plugin of wp-redis
2. how to setup in multisite please?

Thanks.
