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.
