I think what I want must be eminently measurable. The total bytes served
from squid is the sum of the sizes all the hits + all the misses. If there'd
been no squid, every cache hit would have resulted in a fetch from the
internet, so the bandwidth gained is =
cache item size X number of hits for that item

No, that of course won't answer me because I'd not be comparing like with like.
