Internet Archive audio server redirect does not support CORS headers

[benwbrum]

If I try to import https://iiif.archive.org/iiif/3/wreck-of-the-old-97_202102/manifest.json into ProjectMirador, I get this error in my JS console:

Access to audio at 'https://dn720304.ca.archive.org/0/items/wreck-of-the-old-97_202102/Wreck%20Of%20The%20Old%2097.wav' (redirected from 'https://archive.org/download/wreck-of-the-old-97_202102/Wreck%20Of%20The%20Old%2097.wav') from origin 'https://projectmirador.org' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Strangely, this does not appear to be a problem on the Aviary IIIF player

We've just tested it now in the meeting and it seems to be working although we both tested this earlier and saw it broken. I think it needs some more investiagion on the forwarding to see where the CORS headers are missing.

One that has worked in the past: https://iiif.archive.org/iiif/3/cc4ia-Polar_Plunge_Promo_-_2018/manifest.json

Just adding that @benwbrum 's example now appears to work for me in Mirador. 🤷🏻

Closing seemed to be a tempoary issue which was fixed. Will re-open if we discover more issues with CORS.
