Comment 8 for bug 996151

@Jason,
  I'm curious as to what sort of link you're on that shows that greatly improved behavior.
  In my (admittedly small) testing, I tested against local apache mirrors, remote mirrors through a proxy...

  I could very well have been missing something obvious, or just being woefully ignorant.
  I admit to being not terribly well educated on this topic, and relied heavily on the advice of Robert Collins (author of squid) to give direction.
