Dynamic web platforms running PHP or Node.js backends quickly choke under sudden traffic surges unless backed by aggressive edge reverse proxies. Properly configured LiteSpeed and Nginx micro-caches serve dynamic pages in sub-10ms response times.
The Principle of Micro-Caching
Even caching dynamic pages for just 5 to 10 seconds reduces database query loads by up to 98% during viral traffic spikes while preserving near real-time content freshness for visitors.
LiteSpeed Server Cache Optimization
- Direct Kernel Integration: Serving cached static assets directly from kernel memory without touching the PHP execution engine.
- ESI (Edge Side Includes): Selectively punching holes in cached pages to load personalized user session widgets dynamically.
- Automated Tag-Based Purging: Invalidating only the specific articles and category archives updated during content publishing.
