説明

LumenCache implements a RAM-first full-page cache with a WordPress
advanced-cache.php drop-in. On a cache HIT, the drop-in serves complete HTML
before the normal WordPress bootstrap and database queries. This early-response
path reduces application-layer work and keeps repeat page requests fast across
Nginx, Apache, and LiteSpeed.

The cache is designed to fail open when its storage layer is unavailable, so a
cache connection problem does not take the WordPress site offline.

Research Foundation

Academic Reference:
“Dynamic Resource Mapping in Zero-Reload Server Architectures: Eliminating
Application-Layer Latency and Extension Dependency in High-Concurrency CMS
personalised requests continue through the full WordPress stack.

This architecture is intended to reduce repeated bootstrap work, database
queries, and extension overhead while preserving WordPress compatibility. It
also provides a practical bridge between academic performance research and
everyday publishing workloads, including content-heavy sites, WooCommerce
catalogues, and membership-driven pages.

Research author: Dean Nasrul Eam — Light & Composition University.

Eight-Subsystem Architecture

  1. RAM-First Full-Page Cache Engine — PHP stores complete HTML at
    shutdown and resolves repeat requests from the in-memory cache layer.
  2. Nginx / Apache Proxy Bridge — Static or dynamic server config bypasses
    PHP entirely for cache hits.
  3. Selective Bypass Cookie Router — sys_active_state cookie routes
    logged-in users and cart-active visitors to live PHP.
  4. Application Driver Profile Engine — Auto-detects WooCommerce,
    LearnDash, LifterLMS, MemberPress, BuddyBoss and registers tailored bypass
    rules and invalidation hooks.
  5. Surgical Cache Invalidation — Post save / nav menu / widget / theme
    switch events trigger precise per-URL or full purges.
  6. REST API State Endpoint — /wp-json/lumencache/v1/user-state serves
    personalised fragments for skeleton-hydration clients.
  7. Skeleton Hydration DOM Worker — skeleton-hydration.js replaces cached
    placeholders with live content on load.
  8. WP-CLI Management Interface — flush, flush-url, status commands.

Configuration (optional)

All settings are configurable from LumenCache Settings in the WordPress
admin. Optionally override any setting via wp-config.php — constants always win:

define( 'LUMENCACHE_REDIS_HOST',          '127.0.0.1' );
define( 'LUMENCACHE_REDIS_PORT',          6379 );
define( 'LUMENCACHE_REDIS_SOCKET',        '' );
define( 'LUMENCACHE_REDIS_PASSWORD',      '' );
define( 'LUMENCACHE_REDIS_DATABASE',      0 );
define( 'LUMENCACHE_REDIS_TIMEOUT',       1.0 );
define( 'LUMENCACHE_REDIS_PREFIX',        'cache:' );
define( 'LUMENCACHE_CACHE_TTL',           86400 );
define( 'LUMENCACHE_CACHE_SALT',          '' );
define( 'LUMENCACHE_CACHE_QUERY_STRINGS', false );
define( 'LUMENCACHE_PROXY_PASSWORD',      '' );

WP-CLI

wp lumencache flush
wp lumencache flush-url https://example.com/page/
wp lumencache status<h3>Privacy</h3>

LumenCache stores rendered page HTML and cache metadata in the in-memory cache
service configured by the site administrator. It does not send cache contents,
visitor data, or analytics data to a third-party LumenCache service. The
optional user-state endpoint returns only the requested dynamic values to the
requesting browser; sites should review those values and their own privacy
policy before enabling personalized hydration.

FAQ

Getting a 502 Bad Gateway on Nginx after activating or during WooCommerce use?

Nginx has a default fastcgi_buffer_size of only 4KB–8KB. When combining rich caching headers with WooCommerce session cookies, the upstream response header exceeds this limit. Nginx immediately terminates the connection with:
upstream sent too big header while reading response header from upstream, resulting in an instant 502 Bad Gateway error.

To resolve this, add the following FastCGI and proxy buffer directives to your Nginx configuration (within the http {}, server {}, or PHP location block):

fastcgi_buffer_size 32k;
fastcgi_buffers 16 16k;
fastcgi_busy_buffers_size 32k;
proxy_buffer_size 32k;
proxy_buffers 16 16k;
proxy_busy_buffers_size 32k;

After adding these directives, test and reload Nginx:
nginx -t && systemctl reload nginx

Why are 0 pages cached?

Two common causes:
1. Nginx config not applied — visit Server Setup and paste the config blocks.
2. WooCommerce session cookie — fixed in v1.1.0. Previous versions bypassed
the cache for all visitors on WooCommerce sites due to the always-present
wp_woocommerce_session_* cookie.

Why can key salting affect server-level caching?

When LUMENCACHE_CACHE_SALT is set, PHP stores keys as SHA-256 hashes. A
server-level configuration must use the same key strategy or it will produce
cache misses. Disable the salt for a plain-key configuration, or use the
compatible hashed-key server template.

Does LumenCache work with LiteSpeed?

Yes. LiteSpeed supports Apache-compatible .htaccess rewrites. LumenCache uses
the Apache proxy mode on LiteSpeed. For better performance, ask your host
which in-memory cache acceleration options are available.

Can I still use wp-config.php constants?

Yes — constants always take precedence over admin settings. If you define a
constant, the corresponding field in the Settings tab is shown locked (read-only).

変更履歴

1.6.34 (September 15, 2026)

  • PRO COMPATIBILITY: Hardened lumencache_is_pro_active() to verify defined( 'LUMENCACHE_PRO_VERSION' ) && get_option( 'lumencache_pro_status' ) === 'active', preventing false positive status if the Pro add-on is deactivated or uninstalled.
  • CLOUDFLARE EDGE SYNC: Hooked lumencache_purge_urls into single-URL purge operations (purge_url), ensuring Admin Bar “Purge This URL” and WP-CLI flush-url actions automatically purge Cloudflare edge cache alongside local Redis.
  • APACHE & LITESPEED TELEMETRY: Added Pro hit-counter telemetry parity to the pre-bootstrap proxy (server/lumen-cache-proxy.php) on cache HITs, and updated Drop_In::write_config() to synchronize compiled pro_active state to deployed proxy files.
  • ADMIN ACTIONS CONTEXT: Injected from_tab retention to the Cloudflare purge form on the Cache Controls page, keeping administrators on their current tab after purging.

1.6.33 (September 15, 2026)

  • ADMIN BAR: Added contextual “Purge This URL” sub-node when viewing frontend content, enabling instant single-URL cache invalidation directly from the toolbar without flushing the entire site.
  • DASHBOARD WIDGET: Retained administrator on wp-admin/index.php after flushing cache via redirect_to handling, complete with dismissible success notice and refined button hover styling.
  • WP-CLI: Enhanced wp lumencache status with --format support (table, json, yaml, csv) and drop-in / WP_CACHE status visibility; aligned flush-url output with semantic WP-CLI warning conventions.
  • REST API & HOLE-PUNCHING: Automated WooCommerce cart and session initialization (wc_load_cart) during REST API user-state hydration requests; added LifterLMS course-progress resolution support.
  • REST API EXTENSIBILITY: Introduced lumencache_user_state_keys and lumencache_resolve_user_state_{$key} filters for developer extensibility.
  • NONCE HARDENING: Supported both query parameter and X-WP-Nonce header authentication across REST user-state hydration and Admin Bar AJAX flush handlers.

1.6.32 (September 15, 2026)

  • SETTINGS & CONNECTION TEST: Added native AJAX Redis connection testing (lumencache_test_redis) supporting both phpredis and Predis drivers, Unix sockets, host/port, database indexes, connection timeouts, and authentication passwords.
  • UI & TAB NAVIGATION: Implemented seamless browser URL synchronization (history.replaceState) on sidebar tab switches, preventing stale tab states across page reloads.
  • QUICK SETUP TRACKER: Enabled 1-click execution for Apache / LiteSpeed rewrite rule generation directly from the Quick Setup Tracker on the Overview tab, eliminating unnecessary navigation steps.
  • ADMIN ACTION REDIRECTS: Added contextual tab and from_tab state retention across all admin actions (cache flushes, drop-in deployment, settings save, salt save, and rewrite operations), preserving the user’s active view after every submission.
  • SETTINGS HARDENING: Enhanced password field handling to preserve special characters and ensured default namespace fallback (cache:) when clearing key prefix.
  • SETTINGS CACHE: Added Settings::reset_cache() method to reset in-process configuration memory.

1.6.31 (September 15, 2026)

  • NGINX: Synchronized nginx_map_block() and sample Nginx configurations with wp-postpass_ and comment_author_ cookie bypass rules, preventing cached responses for unlocked password-protected posts and returning commenters.
  • APACHE & LITESPEED: Enhanced .htaccess rewrite rules to directly exclude /feed/ requests and XML sitemaps before proxy evaluation, avoiding unnecessary PHP execution overhead.
  • APACHE & LITESPEED: Added explicit wp-postpass_ and comment_author_ cookie rewrite conditions to .htaccess configuration.
  • PROXY DEPLOYMENT: Hardened Htaccess::deploy_proxy() to verify and ensure target upload directory existence with wp_mkdir_p().
  • PRE-BOOTSTRAP PROXY & DROP-IN: Aligned socket connection timeouts, \Redis::OPT_READ_TIMEOUT, Predis read_write_timeout, and comment_author_ cookie bypass across both server/lumen-cache-proxy.php and server/advanced-cache.php.

1.6.30 (September 15, 2026)

  • TIMEOUT: Added explicit connection and read timeouts for phpredis (\Redis::OPT_READ_TIMEOUT) and Predis (read_write_timeout) to protect PHP worker processes from hanging on stalled Redis operations.
  • SOCKETS: Added explicit timeout to phpredis Unix socket connections and cleaned up TCP host/port parameters on Predis socket connections.
  • LATENCY & QUERY OPTIMIZATION: Implemented in-memory memoization and transient caching for key_count() to eliminate redundant full-keyspace SCAN operations across admin page views.
  • ARRAY SAFETY: Hardened delete() and delete_pattern() against PHP 8.1+ argument unpacking errors by guaranteeing integer-indexed array keys with array_values().
  • TELEMETRY: Standardized memory extraction in memory_used() across both phpredis and Predis drivers for accurate RAM usage reporting.
  • RECONNECT: Added reconnect() and get_prefix() helper methods to Redis_Connector.

1.6.29 (September 15, 2026)

  • FIX: Protected logged-in sessions in Cookie Router (clear_active_cookie()) when WooCommerce cart is emptied or subscriptions stop, ensuring sys_active_state cookie is preserved while user remains logged in.
  • FIX: Expanded WooCommerce bypass routes across early drop-in, proxy, and application drivers to include /wc-api/ to safeguard payment gateway callbacks and webhooks from being cached.
  • FIX: Hooked woocommerce_variation_set_stock to immediately purge stale caches when variable product inventory levels are updated.
  • HARDENING: Dynamic cookie path and domain resolution in send_cookie() with reverse proxy HTTPS detection via HTTP_X_FORWARDED_PROTO.

1.6.28 (September 15, 2026)

  • FIX: Added universal WordPress DONOTCACHEPAGE constant compliance in both bypass decision and shutdown write checks.
  • FIX: Added contextual bypass checks in Cache_Engine for 404 pages, post draft previews, customizer previews, robots.txt, trackbacks, XML-RPC, and password-protected posts (wp-postpass_ cookie).
  • HARDENING: Added PHP fatal error detection (error_get_last()) during output buffer capture to guarantee broken pages or fatal errors are never written to cache.
  • INVALIDATION: Added surgical invalidation for post status transitions (transition_post_status) so unpublishing or trashing a post immediately clears its cached HTML from Redis.
  • INVALIDATION: Added post comment and review invalidation hooks (comment_post, edit_comment, wp_set_comment_status, delete_comment, trashed_comment, spammed_comment) and created_term.
  • PERFORMANCE: Optimized post purging with batched multi-key Redis DEL execution and automated invalidation of all taxonomy archive URLs (categories, tags) associated with the updated post.
  • REVERSE PROXY: Aligned HTTPS scheme detection across Cache_Engine, advanced-cache.php, and lumen-cache-proxy.php behind SSL-terminating reverse proxies.

1.6.27 (September 15, 2026)

  • FIX: Synchronized pre-bootstrap Apache/LiteSpeed proxy (lumen-cache-proxy.php) with complete feed bypass rules (/feed/ and ?feed=) to prevent XML feeds from caching as HTML.
  • FIX: Expanded XML sitemap bypass in both advanced-cache.php and lumen-cache-proxy.php to cover core WordPress (wp-sitemap), standard sitemaps (sitemap_index), and paginated variants.
  • FIX: Automated compiled configuration snapshot synchronization into deployed wp-content/uploads/lumen-cache-proxy.php on file deployment and settings save.
