Configures CDN/edge delivery and a WAF — cache keys and Cache-Control/Surrogate-Control, stale-while-revalidate, tag/path purge wired into deploy, origin shielding with request collapsing, edge TLS + HTTP/3, and a managed OWASP ruleset with edge rate-limiting and bot/DDoS mitigation rolled out detect-then-enforce — to raise cache hit-ratio and absorb attacks before the origin.
