Well, that's where I'd start. Look for some sort of correlation between
these hosts or the proxies they're using. Maybe temporarily turn on
logging of user-agents (to a seperate log file if you don't want to mess
up your logs) and see what falls out. Without seeing the data in the
logs, there's not much more I can do besides more wild guessing.
The only other wild guess I'd have is that the users in question have
some sort of adblock filter or sit behind proxies that filter. The
originally requested file isn't filtered, but the redirected file
matches a rule so doesn't get requested.
