Hello,

We're exploring the new URL Filter capability and we managed change the SimpleURLFilter so that it could work on macOS.

However, on macOS it won't work as even when signed for debugging it tries to use Apple's OHTTP Relay.

Failed to fetch Token Issuer Directory. <NSHTTPURLResponse: 0xca10ca580> { URL: https://gateway.icloud.com/pat-issuer-directory?issuer=localhost } { Status Code: 503

So I have two questions:

Will it be possible to debug URL Filter locally on macOS?
Even more important: how can I send a capability request so that our OHTTP Gateway could be used? I checked everywhere, but it seems there's simply no way to request this capability at this moment.

1. Will it be possible to debug URL Filter locally on macOS?

I’d expect that to work. I actually think I can see what’s going wrong here. Please file a bug about this, and then reply here with your bug number so that I can update it with my findings.

2. Even more important: how can I send a capability request so that our OHTTP Gateway could be used?

Hmmm, I thought we’d sorted that out already, but perhaps not. Lemme research that and get back to you.

I was right, but the info is tucked away:

The PIR side of this is documented in the PIRService open source Swift package.
The How to onboard with an Oblivious HTTP relay hosted by Apple section has links to the submissions forms. Scroll down to the bottom.

Oh, and don’t forget to post a bug about regarding your inability to filer locally on the Mac. I’d like to get that sorted out.
