Introducing Zero Round Trip Time Resumption (0-RTT)

What this post added

This post introduces Zero Round Trip Time Resumption (0-RTT) as a performance-enhancing feature for TLS 1.3. It explains how 0-RTT reduces the number of round trips required for establishing secure connections, particularly for resumed connections, leading to faster website loading times. The post details the latency costs of network transmission and HTTPS handshakes, and quantifies the performance gains of TLS 1.3 with 0-RTT compared to previous TLS versions. It also discusses browser support and provides a live demo to showcase the feature's impact.
