CDN Caching And Edge Acceleration Patterns

Use When

• Global users require low-latency content delivery
• Origin load or spikes affect frontend reliability

Workflow

1. Classify cacheability by asset and response type.
2. Define TTL, revalidation, and purge strategy.
3. Configure origin shielding and geo failover behavior.
4. Apply signed URLs/cookies and edge access controls where needed.
5. Monitor hit ratio, origin offload, and stale-content incidents.
