CDNcachelocaties
CDNcachelocaties refers to the distributed set of edge locations within a Content Delivery Network (CDN) where copies of content are cached to serve user requests close to their location. These cache locations, also known as edge nodes or Points of Presence (PoPs), are geographically dispersed to minimize latency, reduce origin server load, and improve availability.
Operation: When a user requests a resource, the request is routed to a nearby CDN edge node.
Cacheability and policies: Cacheability depends on HTTP headers (Cache-Control, Expires, ETag) and on CDN policies. TTL
Benefits and considerations: Key benefits include reduced latency, lower bandwidth costs, and improved fault tolerance. Challenges
