Nginx Cache Purge Preload

NPP lets WordPress users manage Nginx Cache Purge and Preload (FastCGI, Proxy, SCGI, UWSGI) operations directly from the WordPress admin dashboard — actively warming the cache via site crawl, so your Nginx cache is always preloaded and ready.

NPP is the only Nginx cache plugin that doesn’t just clear the table — it sets the whole banquet. No other Nginx cache plugin comes close to its feature list, purge architecture, preload intelligence on WordPress.

🖥️ Quick WP-CLI

Manage your Nginx cache entirely from the command line. Perfect for automation, cron jobs, panels, and headless workflows.

Purge: wp npp purge | wp npp purge --page-url=<url>
Preload: wp npp preload | wp npp preload --page-url=<url> | wp npp preload --stop
Get Full command list: wp help npp | wp help npp <subcommand>

Features

🧹 Purge All Nginx Cache: Completely clear all cached data stored by Nginx.

🔄 Preload All Nginx Cache: Warm the Nginx cache with the most recent data for the entire website.

🎯 HTTP Purge (ngx_cache_purge): When the Nginx cache module (ngx_cache_purge) is available, NPP uses it as the fastest purge path. Falls back gracefully to index and filesystem purge when the module is not present.

🗂️ INDEX Purge: Leverages the preload-generated URL → Filepath index to directly resolve and purge cache without filesystem traversal. If the cache exists and is valid, purge is executed immediately for near-instant performance.

⚡ RG Purge: ripgrep-powered cache file lookup that replaces slow PHP directory scanning for single-URL purges, enabling near-instant deletes on large or FUSE-mounted caches. Automatically falls back to standard scan if unavailable.

🚀 Auto Preload Nginx Cache: Automatically preloads the cache when Auto Purge is enabled for a POST/PAGE or after the Purge All action.

🧼 Auto Purge Nginx Cache: Purge cache on Post/Page content changes, comment status updates, theme/plugin updates, or when compatible Cache Plugins trigger a purge. Nginx cache is preloaded automatically if Auto Preload is enabled (for the entire site or individual page).

🔗 Purge Scope (Related Pages): Automatically purge related pages such as the Homepage, WooCommerce Shop page, and Category/Tag archives when a single URL is purged. Optionally preload those pages to keep the cache warm.
