Actually, most of it is cacheable; Microsoft simply marks it as non-cacheable. If you don't override that, you may find that 80% or more of your bandwidth is consumed by updates. The problem is that Squid doesn't handle subranges of files very well when there's a cache hierarchy. The child cache, when it gets the request, re-fetches the entire file from the parent cache in order to cut out the subrange. --Brett Glass
