How is this related to squid-1 and apache?
  ie how do squid-2 and squid-3 identify requests which are destined to
the squid-1/apache pair and which out of that pair do they contact?

what does gc-repo.atsi.com resolve to on each box? (IPv4 and IPv6 addresses)
   - does it use DNS or hosts file entries in your test setup?

What do you mean by "redirected to" ?
   a) request sent to squid-3 gets diverted and serviced by squid-2
without going through squid-3?
or
  b) request chained through squid-3 to squid-2 to somewhere?

You are missing '/' at the end of that variable value. But it seems to
work for wget anyway (other software wont, I know this from sad experience).
