NP: regex has an implied .* prefix and suffix on patterns unless you use
the ^ and $ endpoint anchors.

What are the HTTP headers for these requests and replies?
 The 206 status indicates a Range request taking place. But the first
and third log entry indicate a 283KB range out of a 1400 byte rediretion
object being delivered. But weird.

 A quick scan by redbot indicates that the top URL is a redirection (302
as logged first but not second time around) to a URL which responds with
the worlds most annoying Vary header.
"Vary: * effectively makes this response uncacheable." in redbots words.
