Real URLs for AMP Cached Content Using Cloudflare Workers

What this post added

This post introduces the implementation of HTTP signed exchanges using Cloudflare Workers to enable AMP caches to serve content under its origin URL. This addresses the security and attribution issues of AMP by extending authenticity and integrity to cached content. The technical details cover the generation of HTTP signed exchanges using MICE for integrity proofs and CBOR for serialization, signed by the publisher's private key. Cloudflare Workers automate this process, allowing publishers to leverage AMP performance while maintaining origin URLs.
