This plugin, NPP, allows WordPress users to manage Nginx Cache Purge and Preload (FastCGI, Proxy, SCGI, UWSGI) operations directly from the WordPress admin dashboard, enhancing website performance and caching efficiency.
Unlike other solutions that depend on Nginx modules, NPP directly manages cache files without needing to interact with Nginx.
➡️ This approach provides the following benefits:
⚡ Faster – No waiting for Nginx to process cache purges; works without interacting with Nginx. 
🌐 Greater flexibility – Works seamlessly across different architectures, including containerized environments where Nginx may run on a host, in a separate container, or distributed across systems. 
🤖 Automations – NPP is flexible for server-side automations, making it easy to integrate into your workflow.
⚠️ IMPORTANT:
NPP is feature rich, completely free & functional and great for users who manage their own servers and have technical know-how. For those with less technical experience, pre-made Bash scripts are available, making it easy to get started and benefit from the plugin.

Nginx Cache Purge Preload

The most comprehensive solution for managing Nginx (FastCGI, Proxy, SCGI, UWSGI) cache operations directly from your WordPress dashboard.

Razvan Stanga

Complete WordPress Varnish Cache 3.x/4.x/5.x and Nginx Proxy Cache integration.
This plugin handles all integration with Varnish Cache and Nginx Proxy Cache. It was designed for high traffic websites.
Main features
<ul>
<li>admin interface, see screenshots</li>
<li>console for manual purges, supports regular expressions so you can purge an entire folder or just a single file</li>
<li>supports every type of Varnish Cache implementation, see screenshots for examples</li>
<li>unlimited number of Varnish Cache servers</li>
<li>use of custom headers when communicating with Varnish Cache does not interfere with other caching plugins, cloudflare, etc</li>
<li>Varnish Cache configuration generator</li>
<li>purge key method so you don’t need to setup ACLs</li>
<li>debugging</li>
<li>actively maintained</li>
</ul>
You can control the following from the Varnish Caching admin panel :
<ul>
<li>Enable/Disable caching</li>
<li>Homepage cache TTL</li>
<li>Cache TTL (for every other page)</li>
<li>IPs/Hosts to clear cache to support every type of Varnish Cache implementation</li>
<li>Override default TTL in posts/pages</li>
<li>Purge key based PURGE</li>
<li>Logged in cookie</li>
<li>Debugging option</li>
<li>console for precise manual purges</li>
</ul>
This plugin also auto purges Varnish Cache / Nginx Proxy Cache when your site is modified.
Varnish Caching sends a PURGE request to Varnish Cache / Nginx Proxy Cache when a page or post is modified. This occurs when editing, publishing, commenting or deleting an item, and when changing themes. 
Not all pages are purged every time, depending on your Varnish / Nginx Proxy Cache configuration. When a post, page, or custom post type is edited, or a new comment is added, only the following pages will purge:
<ul>
<li>The front page</li>
<li>The post/page edited</li>
<li>Any categories or tags associated with the page</li>
</ul>
<a href="https://www.varnish-cache.org/" rel="nofollow ugc">Varnish Cache</a> / <a href="https://www.nginx.com/blog/nginx-caching-guide/" rel="nofollow ugc">Nginx Proxy Cache</a> is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. This plugin does not install Varnish/Nginx for you, nor does it configure Varnish/Nginx for WordPress. It’s expected you already did that on your own using the provided config files.
