I tested it and couldn't get this to work to download the CVD files. I 
believed it was because it was trying to repeatedly download full CVD 
files rather than the CDIFFs, but maybe it was something else at my end 
or the Cloudflare throttling not liking my tests at the time I tried it. 
Because cvdupdate worked well and is better, I didn't persue this 
option. If it should work, then I apologise.

Yes, this option is fine if all your clients are on a fast LAN, but not 
when private mirror serves clients over WANs, VPNs, remote Internet 
users, etc

This is exactly what the cvdupdate method is supposed to help with. That 
does NOT use the 'PrivateMirror' option with the private mirror as you 
originally said it did.
