that does not mean the proxies were fine-tuned. that can indicate they
were not :)

along with cache digests, ICP can be used to detect if one of siblings has
object in its cache. That's why I recommend using it.

see http://squid.visolve.com/squid/squid24s1/glossary.htm for difference
between parent and sibling.

If you have more 2nd-level squid caches with different links, you probably
should set up them all as parents to your 1st-level proxy and as siblings
to each other (just for sure) and set up ICMP on all of them to be able to
know which proxy is closest to the requested data and fetch the data using
that parent.
