The first obvious thing that stands out to me from this is that these are
HTTPS connections, not HTTP, so I'm going to let someone more familiar with
Squid's current handling of HTTPS pass further comment, except for my question
further down...

When the unexpected authentication dialog appears:
1. what page do you see if you fail to authenticate correctly - is it from the
origin server cdn0.vox-cdn.com (in this case) or is it the page your users
would see if they failed to correctly authenticate to squid in the first
place?
2. can you authenticate, and get the expected page from the origin server, by
using the user's Squid credentials?

Antony.
