The Cache Purger vs Varnish/Nginx Proxy Caching

The Cache Purger takes the headache out of cache management. Instead of juggling a dozen different cache-clearing buttons across your stack, this plugin hooks into WordPress actions and fires them all at once — automatically, on a schedule, or with a single click from the admin bar. It covers the full spectrum: popular caching plugins, managed hosting environments, PHP-level caches (OPcache, APC, WinCache), server-level caches (Nginx, Varnish, PageSpeed), in-memory stores (Redis, Memcache, Memcached), and external CDN/WAF APIs (Cloudflare, Sucuri, Fastly). Every purge is configurable. Choose which cache types to include, which WordPress events should trigger a purge, and which specific posts, pages, CPTs, or field groups to exclude. You can also run purges on a WP Cron schedule, or kick one off manually via WP-CLI.

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: The front page The post/page edited Any categories or tags associated with the page Varnish Cache / Nginx Proxy Cache 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.
