In today’s digital world, website performance is crucial for user experience and business success. While CDNs are known for optimizing static content, they also enhance dynamic content delivery. Dynamic content, generated in real-time based on user data or interactions, often causes performance bottlenecks. Modern CDNs use edge computing, smart caching, TCP/HTTP optimizations, and route enhancements to reduce latency and origin load. Techniques like cache-control headers, content segmentation, and origin shield architectures help implement these improvements. Studies show a 30-50% reduction in load times after CDN integration. Challenges include cache invalidation and data freshness, but solutions like purge APIs and edge personalization help. Future trends include AI caching, powerful edge nodes, and better security integration.
