Other point: mirrors usually have a legal and published URL in their own
right, irrespective of any synthesized mapping from URI-space to their
instance of the cloned data.
http://mirror.aarnet.edu.au/FreeBSD is a documented published
URL to reach the same resources as http://www.freebsd.org/
Caches do not exist as terminal objects in themselves (for their content
that is) in the same way.
I think this distinction matters because in compiling the set of rewrite
rules for redirection in caches, to supplement any inter-cache ICPlike
behaviour, you need a complete set of the known URL of the mirrors to
make a complete set of the possible (and hence derive the preferential)
rewrite rule to effect.
