How CloudFlare Rocket Loader Redefines the Modern CDN
Jun 10, 2011Matthew Prince

Summary
Introduced Rocket Loader, a new feature that addresses script blocking and asynchronous loading. Rocket Loader ensures scripts do not block page rendering, loads them asynchronously, bundles script requests into a single stream, and uses LocalStorage for intelligent caching. It aims to provide SPDY-like performance benefits across most browsers and smartphones by modifying HTML on the fly.
