  25 min read • Published on January 15, 2023

  A comprehensive analysis of web protocol evolution revealing how HTTP/1.1’s application-layer bottlenecks led to HTTP/2’s transport-layer constraints, ultimately driving the adoption of HTTP/3 with QUIC. This exploration examines TLS handshake optimization, protocol negotiation mechanisms, DNS-based discovery, and the sophisticated browser algorithms that determine optimal protocol selection based on network conditions and server capabilities.
