Yes, a copy is made.  This is "traditional" in the sense that the
client code ensures that even if an original upstream server goes
away, cached files stay accessible for a while.  I can also see how
this might be less valuable than just getting at the files with
minimum overhead.  Does anyone think we need to have both as options?
