Attached, although I didn't see any difference in the log between using 
the new Direct Connection option and the old one.

I think you nailed it. I tried again this morning and the first time I 
ran setup, it did contact our local site, but it did not on subsequent 
runs (even to see if the file has changed). I then modified our web 
server to add a "Cache-Control: no-cache" header and cleared the Windows 
cache. After that, setup retrieved the setup.xz file from our server on 
every run.

For background, we host our own partial repository of locally built 
packages, so the setup.xz our server provides is not complete. It would 
be incorrect for setup to assume that the setup.xz downloaded from one 
site is identical to the ones available from the other selected sites.
