Real speed: HTTP/2 HPACK cuts redundant web header bloat

HTTP/2 solves HTTP/1.1 latency by replacing text-based sequential requests with a multiplexed binary framing layer, allowing concurrent data over one connection.

If you want to understand modern web architecture, you have to understand the physical limitations of TCP and how HTTP/2 engineered around them. This deep-dive breaks down the foundational shift from the early web to high-speed, microservice-driven networks.

You will learn exactly why HTTP/1.1 created severe application-layer head-of-line (HoL) blocking, and how HTTP/2 solves this by introducing a 9-byte binary framing layer. Instead of opening multiple resource-heavy TCP connections to load a webpage, HTTP/2 interleaves independent streams over a single connection (multiplexing).

We also explore the mechanics of HPACK, a stateful compression algorithm that eliminates redundant header bloat (like `User-Agent` strings) by replacing text with integer indices via Static and Dynamic tables. Finally, we break down why Server Push failed, how ALPN negotiates connections seamlessly during the TLS handshake, and why gRPC relies entirely on HTTP/2 multiplexing to function.
