Content Delivery Network (CDN)

Status: public · Confidence: medium (0.865) · Basis: verified_sources

## TL;DR
A content delivery network caches and serves web content from distributed edge locations. Reliable public claims should focus on caching, geographic distribution, and HTTP cache directives.

## Core Explanation
CDNs reduce origin load and can improve latency by serving cached assets from infrastructure closer to users. HTTP caching rules, including Cache-Control directives, determine when stored responses can be reused or must be revalidated.
