A one-page checklist to audit your video delivery before you sign a CDN contract: confirm a global PoP footprint for your regions, set long segment TTLs and short live-manifest TTLs, keep the cache key free of per-viewer query strings, turn on an origin shield with request collapsing, instrument the byte-based offload ratio (not just request cache-hit ratio), and run the offload-vs-origin-egress sanity check from the article's worked example.

Our seven-volume handbook covers the full video stack; start with Volume 3 for CDNs, caching and streaming economics, then Volume 2 for HLS and DASH packaging and Volume 1 for encoding. Written by Nikolay Sapunov, CEO at Fora Soft.
