A flexible and customizable event driven cache purge plugin to work in conjuction with Nginx configured as a front end proxy to a WordPress install.

If you have a single WP site without custom post types or mobile support the <a href="https://wordpress.org/extend/plugins/nginx-proxy-cache-purge/" rel="ugc">Nginx Proxy Cache Plugin</a> is simpler and will probably meet your needs.

<h3>Caching Deployments</h3>
For NGINX Stack (cPanel/WHM): 
– ea-NGINX (reverse proxy caching) is meant to be 2nd-level 
– Make sure your WP site also has on-site caching, like WP Super Cache 
– You can go further with caching: browser-caching assets!
For LiteSpeed Stack: 
– Use the <a href="https://wordpress.org/plugins/litespeed-cache/" rel="ugc">LiteSpeed Cache plugin</a> 
– See <a href="https://docs.openlitespeed.org/config/lscache/" rel="nofollow ugc">LiteSpeed Cache documentation</a> for configuration
3-layer Cache (NGINX): 
1. NGINX Caching Proxy (ahead of Apache) 
2. WP Super Cache, WP Rocket, etc on-site 
3. htaccess/etc rules for Browser Caching
This way, you can ensure maximum efficiency!
The key is to purge when stale, so properly configuring your WP Plugin Cache is critical to ensuring that you don’t end up with cache misses due to stale data that could’ve/should’ve been purged by garbage collection, preloading, etc, rule-sets.
<h3>Updating from v1 to v2.x.x</h3>
On every website running the plugin, check that:
<ol>
<li>Website is reporting v2.x.x plugin version.</li>
<li>Plugin has been activated post-update. *</li>
<li>Config exists in the plugin settings.</li>
<li>API status checker reports OK.</li>
<li>/wp-content/tnc-toolbox-config/ folder is gone.</li>
</ol>
(* Change to main plugin file name may result in deactivation)
<h3>Verifying cP+WHM Logs</h3>
If you’d like to ensure actions are firing properly at a deeper level:
<ol>
<li>WHM > Tweak Settings > Logging > Enable cPanel API Log > On</li>
<li>WHM > Terminal > <code>tail -f /usr/local/cpanel/logs/api_log</code></li>
<li>WordPress > Update a Post/Page, or explicitly Purge</li>
<li>WHM > Terminal > You should see the action fire!</li>
<li>WHM > Terminal > Ctrl+C to close the tail</li>
</ol>
Note: To do this, you require <code>root</code> access to the Server.
