Nginx Cache Purge Preload vs Lite Cache

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.

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. 📡 Preload Feeds: Take full control of RSS/Atom feed caching. Decide site‑wide or per‑URL whether the main feed, per‑post comment feeds, and taxonomy RSS feeds are included in the preload process. ⏰ Schedule Nginx Cache Purge & Preload via WP Cron: Automate the purge and preload process using WordPress Cron jobs. 🧭 Proxy Support for Preload: Route preload requests through a proxy server for edge-case environments and containerized deployments. ⏱️ Live Preload Progress Monitoring: Watch the Nginx cache preload process in real time — complete with a dynamic progress bar, currently processed URL, 404 tracking, server load, and total completion time. 🌐 Remote Nginx Cache Purge & Preload via REST API: Remotely trigger cache purging and preloading through REST API endpoints. ⚙️ Manual Nginx Cache Purge & Preload: Allow manual purging and preloading of cache through the table view in the Advanced Tab. 📚 Nginx Cache Analyzer: Full HIT/MISS cache analyzer dashboard, from the last preload crawl with what is currently stored in the Nginx cache. Instantly spot uncached pages and Purge or Preload them directly in the Advanced Tab. 🪫 Preload All MISS: A targeted replacement for the expensive Preload All. Instead of purging and re‑caching everything (Preload All), it targets and populates only the cache entries that are not yet warmed. Perfect for sites with high cache coverage (>50%) where a full Preload All be wasteful. 🔍 On-Page Nginx Cache Purge & Preload: Manually purge and preload Nginx cache for the currently visited page directly from the frontend. 🗝️ Custom Cache Key Support: Define a regex pattern to parse URLs based on your custom _cache_key format. 📊 Monitor Plugin and Nginx Cache Status: Monitor plugin status, cache status, and Nginx status from the Status tab. 📈 Cache Coverage Ratio: Live gauge in the WordPress dashboard widget showing the cache coverage ratio, based on the last preload snapshot. Refreshable on demand without a page reload. ☁️ Cloudflare APO Sync: Automatically mirrors NPP purge actions to Cloudflare APO to keep edge cache synchronized with your Nginx cache. 🔴 Redis Object Cache Sync: Coordinates cache invalidation between NPP and Redis Object Cache during NPP-driven operations. NPP Purge All and Preload workflows handle Redis flushing at the appropriate stage to ensure both cache layers stay aligned. 🛒 WooCommerce Auto-Purge: Automatically purges Nginx cache when WooCommerce product stock quantity changes, stock status changes (in stock / out of stock / on backorder), or when an order is cancelled and stock is restored. 🖲️ WP-CLI Support: Manage Nginx cache directly from the command line. Purge and preload cache, view status reports, inspect logs, update settings, flush cache, and manage scheduled tasks without accessing the WordPress admin dashboard. 🔒 Concurrent Purge Serialization: Atomic lock mechanism prevents simultaneous purge operations from colliding, ensuring cache integrity during concurrent admin actions or background events. 🧩 Modular by Design: Easily integrate with external scripts and automation tools. 🖥️ User-Friendly Interface: Easy-to-use AJAX-powered settings, integrated into the WordPress admin bar and dashboard for quick access. 📋 Admin Notices and Logs: Receive notifications and view logs for plugin status and all cache-related actions within the WordPress admin area. 📧 Email Notifications: Receive email alerts upon completion of preload actions, with customizable templates to suit your needs.

New! The Lite Cache technology is now part of Hyper Cache. You should migrate to Hyper Cache, Lite Cache won’t be update anymore (other than important fixes). Lite Cache is an ultra efficient cache plugin. It’s small and lite because it does only one thing: caching. Lite Cache is compatible with gzip compression and handles it automatically. Lite Cache can detect mobile devices and use a different theme for them creating a separate cache. Lite Cache works even with commenters, people who left a comment in the past. Other caching plugin usually are not able to serve cached content to commenters creating performance issues on higly partecipative blogs. Usage of .htaccess rules is possible using the code generated inside the administrative panel (but pay attention that a too much complex .htaccess seems to slow down more than serving cached pages via PHP). Install it and go to the options panel to find how to configure it.
