HTTP/2 Demo: Under the Hood

This article explains a technical demonstration comparing the performance of HTTP/1.1 and HTTP/2 on a demo page. Two inline frames (iframes) were used, one loading over an HTTP/1.1 CDN and the other over an HTTP/2 CDN. The iframes contained full HTML pages with JavaScript that built image tags in sequential order to highlight the performance gains of HTTP/2. The article also discusses caching policy, a Firefox caching bug/feature, SPDY fallback, and emphasizes that this is a demonstration, not a simulation.
