What It Does

Purge Varnish Cache provides integration between your WordPress site and multiple Varnish Cache servers. It sends a PURGE request to the URL of a page or post every time based on configured actions triggered by the site administrator. Varnish is a web application accelerator, also known as a caching HTTP reverse proxy.

This plugin supports all Varnish versions from 3.x to 6.x and requires only a one-time configuration. It offers admin-socket integration and a Varnish admin interface for status checks. You can manage an unlimited number of Varnish Cache servers and purge custom URLs as needed.

The user interface allows for manual purging, and it includes a single-click option for entire cache purges. Debugging features are also available, and the plugin is actively maintained.

The main purpose of this plugin is to deliver updated content to end users without any delay.
