Introduction

Content Delivery Networks (CDNs) are the backbone of modern web performance. By caching content at edge nodes distributed globally, CDNs dramatically reduce latency and offload traffic from origin servers. However, effective caching is not simply a matter of enabling a CDN and forgetting about it. Striking the right balance between performance — high cache hit rates and low latency — and freshness — minimal staleness and fast invalidation — requires deliberate strategy.
