All the way up to 11: Serve Brotli from origin and Introducing Compression Rules

What this post added

This post introduces end-to-end Brotli compression support, enabling origins to serve Brotli-compressed assets at the highest compression level (11). It details the technical implementation of a Brotli decompressor integrated into Cloudflare's core reverse web proxy and Workers runtime, allowing for the preservation of origin compression levels when specific features like Email Obfuscation, Rocket Loader, SSE, Mirage, HTML Minification, and Automatic HTTPS Rewrites are disabled or managed via Configuration Rules. Additionally, it announces Compression Rules for Enterprise Customers, providing granular control over which content types and file extensions are compressed, and how.
