Readme github.com/alpaunovski/wp-varnish-cache-purger ↗

Purge the Varnish cache that sits in front of your WordPress installation automatically.
This plugin schedules full-site purges and clears individual pages whenever content is published or updated, keeping visitors and search engines in sync with what is stored in CloudPanel + Varnish.

Features

  • Sends HTTP PURGE requests to one or more Varnish endpoints.
  • Schedules periodic purges (default hourly) and lets you choose from any registered cron schedule.
  • Clears the permalink and homepage whenever posts are published or modified.
  • Supports authenticated PURGE requests via a custom header (for protected Varnish instances).

Installation

  1. Copy the plugin folder into wp-content/plugins/wp-varnish-cache-purger.
  2. Activate WP Varnish Cache Purger from Plugins → Installed Plugins.
  3. Visit Settings → Varnish Cache Purger to configure at least one Varnish endpoint.

Configuration

The settings screen exposes the following options:

  • Varnish Endpoints – One base URL per Varnish server (e.g. https://cache.example.com).
  • Schedule Interval – How often WordPress should trigger a full-site purge (defaults to hourly). When you choose the daily interval you can also pick the exact 24-hour time, and the weekly interval adds both a time and day-of-week selector.
  • Paths to Purge on Schedule – Relative paths that will be purged on the schedule (default /).
  • Optional Authentication Header – Header/value pair to send with PURGE requests when CloudPanel or your Varnish tier validates incoming purges.
  • Automatic Post Purge – Toggle purging when a post is first published, on update, and whether the homepage should be included in those bursts.

Notes

  • WordPress cron depends on visits to the site. Make sure WP-Cron runs regularly (or trigger it from the system scheduler) to guarantee scheduled purges fire on time.
  • The plugin issues HTTP PURGE requests. Verify that your CloudPanel/Varnish configuration listens for PURGE and routes the call to the correct cache node.
  • No automated tests were executed in this environment because the local PHP binary is unavailable.
