Using WordPress Domain Mapping with CDN Redirects?

Hi,

Some time ago I started this discussion:

https://premium.wpmudev.org/forums/topic/domain-mapping-breaks-cdn-redirects

We got sidetracked, but we finally tried the solution recommended by Ulrich, and we still have the issue. I'm wondering if Ulrich and/or anyone else can revisit it and make a recommendation?

Thanks,

Mark
