Reqad Cache Purger for Nginx

Reqad Cache Purger keeps an Nginx FastCGI page cache in step with WordPress. It adds a « Purge Nginx Cache » button to the admin bar for clearing the whole site, and purges the affected pages by itself whenever content changes.

It works with nothing configured: the plugin sends an HTTP request to a /purge location that Nginx handles, and the caching policy itself lives entirely in your Nginx configuration. A Settings page exists for the optional extras – a background cache warmer, a purge-endpoint override for sites behind a proxy, and a cache self-test – but you can ignore all of it.

What it purges

• Admin-bar button – the entire cache, in a single wildcard request.
• A post or page published, updated, unpublished or trashed – its permalink, the home page and its public taxonomy archives.
• A WooCommerce product – the above, plus the shop page.
• A term created, edited or deleted in any public taxonomy – its archive and the home page.

Post types with no front-end URL (menu items, revisions, WooCommerce orders and similar) are skipped, because they were never cached in the first place.

Requirements

This plugin does not cache anything itself – Nginx does. It requires Nginx built with the ngx_cache_purge module from https://github.com/nginx-modules/ngx_cache_purge – the actively maintained continuation of Piotr Sikora’s original module, which passed through torden’s fork around 2017. If you have seen it called « the Torden fork », that is the same lineage.

The abandoned FRiCKLE repository will not work: the admin-bar button clears the site with a single wildcard request, and wildcard purging landed after FRiCKLE development stopped around 2015.

Full Nginx configuration, including a tested FastCGI cache setup with WooCommerce-safe bypass rules, is in README.md in the plugin folder.
