Only getting 404 through proxy

Hi, @edavidson. I looked for those request ids and I don’t see them in our system. It is possible there is a service worker for that site on your local browser? I ask because this is the most common reason people see x-nf-request-ids that we have no record of.

What happens is that case is that the service worker is returning an old HTTP response which includes an x-nf-request-id which is from over 30 days ago and therefore isn’t in the stored logs (which only go back 30 days).

We have more information about service workers here:
