I'm thinking in adding #ONI proxyUrl support in the frontend.
Currently if a request to a remote #ActivityPub object fails - either due to CORS, or because of authorized fetch - I just display a fallback link to it.
I'm wondering if I can do a two step approach, if the request to the resource fails with 401-403 (for secure fetch) or 400 (for CORS failures) I try to redirect the request through the proxyUrl mechanism.
Only if that fails too, I fallback to something else.
