Technical Difficulties:

In properly configured Nginx servers, it is not strictly necessary to have separate PHP-FPM-USER (as a known WEBSITE-USER or PHP process owner) and WEBSERVER-USER (commonly, nginx or www-data), but there are scenarios where separating these users can enhance security and performance. Although this configuration is recommended as a standard, It leads to difficulties in purging and preloading the cache by the PHP process owner. When the PHP-FPM-USER and WEBSERVER-USER are different, the PHP process owner may not have the necessary permissions to manage cache files created by the WEBSERVER-USER, as the PHP process owner may be unable to read, write, or delete cache files owned by the WEBSERVER-USER.

Proposed Solution by NPP:

In case your current Nginx web server setup involves two distinct users, WEBSERVER-USER and PHP-FPM-USER, the solution proposed by NPP involves combining Linux server side tools inotifywait with setfacl to automatically grant read/write permissions to the PHP-FPM-USER for the corresponding Nginx Cache Paths (owned by WEBSERVER-USER), facilitated by server-side bash scripting. Users need to manage inotifywait and setfacl operations manually or use the provided below one liner basic automation bash script for fully functional purge and preload actions provided by this plugin.
