What is the issue or error you’re encountering

Does the pre-signed URL support cache when using GET from R2 (or more precisely, does the pre-signed URL support CDN when retrieving object from R2)? Or you have to use cache API through a worker to use cache? Thank you.

You’d have to use the Worker approach.

  1. Pre-signed URLs only work on <accountid>.r2.cloudflarestorage.com

  2. Caching only works on Custom Domains:
