Could you explain more why you were you not able to sign the URLs at request time? Creating an HMAC is very fast.

I’m going to have to look into this today. I assuming generating the URLs hit an API, but if those can happen fast locally that changes things.

Yup, pre-signing is fast and local, without any I/O. It’s just math. You could likely pre-sign thousands of URLs per second if you needed.
