Real URLs for AMP Cached Content Using Cloudflare Workers

Google has implemented HTTP signed exchanges, a crucial component of the emerging Web Packaging standard, which extends authenticity and integrity to content cached and served on behalf of a publisher. This solution allows AMP caches to serve content under its origin URL. The technical details involve using MICE (Merkle Integrity Content Encoding) for proof of integrity and CBOR (Concise Binary Object Representation) for serializing headers and payloads. Cloudflare Workers can automate the generation of HTTP signed exchanges, making it easier for publishers to distribute AMP content with their original URLs.
