原文外掛簡介
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.

“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.

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

Privacy
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.
