Edge Caching Basics
Speed via the edge
Edge caching stores assets at CDN PoPs, using cache keys, TTLs, and invalidation/purge rules to speed delivery and lower origin load.

- ttl
- cache key
- purge
- poP
Configure Keys
Include only needed headers/query in cache keys; normalize.
Set TTLs
Choose TTLs per asset type; use stale-while-revalidate if available.
Purge
Purge on deploys or use versioned asset filenames.
