I am running an Ubuntu 20.04 LEMP server with wordpress installed on it. I am using the nginx.org repository for nginx, but I compiled the cache-purge module (ngx_http_cache_purge_module.so) from source with my current nginx.org installation. However, I don't know how to automatically purge the cache using this module.
Is this recompiled module now compatible with my nginx.org installation (i used --compat)
if so
How can I use this module to automatically purge my cache?
You can install for example https://wordpress.org/plugins/nginx-helper/ plugin, which will interface with the nginx cache purge module.
