Hi Jer, thanks a lot for the reply! Clarify things a lot. A few questions though, still hoping we can find a way to fix this:

> This will only work for initial requests.  Subsequent requests (for

> CORS check on those requests.  

Do you mean subsequent requests will not reach code in MediaPlayerPrivateAVFoundationObjC, or CachedResourceLoader does not give us a chance to handle subsequent requests?

Either way, if so, how did we handle this situation in other backends (namely GStreamer backend, as in https://bugs.webkit.org/show_bug.cgi?id=99037 )? Did we leave a loophole there?...

Is this caused by AVFoundation API? If so, that would be a blocker.

Thanks again for your time!
