Implementing TLS 1.3 Zero Round-Trip Resumption: Mechanisms, Pitfalls, and Production Deployment

How TLS 1.3 0-RTT resumption actually works on the wire, why replay attacks make it risky for non-idempotent requests, and the patterns real teams use to deploy it safely behind NGINX, Envoy, and HAProxy.
