HTTP/2 Demo: Under the Hood

What this post added

This post provides a technical deep-dive into the mechanics of HTTP/2 performance improvements through a demo page. It explains how the demo works by comparing HTTP/1.1 and HTTP/2 CDNs using iframes, details the image tile request process, discusses caching policies, and highlights the automatic SPDY fallback mechanism. It also clarifies that the demo is an idealized scenario to visualize benefits, but that typical websites should still see performance gains with HTTP/2.
