Automatically purge cached content when your WordPress site is modified.

Proxy Cache Purge sends PURGE requests to your caching layer (Varnish, Nginx, etc.) whenever content changes — whether you're editing posts, publishing new content, moderating comments, or updating themes and plugins.

1. Install the plugin from WordPress.org or GitHub
2. Activate — the plugin works automatically with most setups
3. Verify it works — go to Proxy Cache → Check Caching and run the End-to-End Cache Test

That's it! For most configurations, no additional setup is required.

A comprehensive 7-step test that verifies both caching AND purging work correctly — no more guessing based on header detection.

When DISABLE_WP_CRON is enabled, purge requests are queued and processed via WP-Cron instead of during page loads. Learn more →

Full command-line control over purging:

wp varnish purge                    # Purge entire cache
wp varnish purge https://site.com/  # Purge specific URL
wp varnish purge --tag=p-123        # Purge by cache tag
wp varnish status                   # Check plugin status
