Overview

Take a signed permanent reference for a blob and turn it into an expiring service URL for download. Note: These URLs are publicly accessible. If you need to enforce access protection beyond the security-through-obscurity factor of the signed blob references, you'll need to implement your own authenticated redirection controller.
