The above balance option makes Squid use round-robin for the
_destination_ websites with multiple IP addresses.
  This is now known to lead directly to problems with IP-based
authentication and sessions on many websites.

All these do by themselves is list the IPs Squid may use. First working
one on the list is always chosen.

To do any selection of addresses you must define some ACL about what
conditions each is to be used for.

Load balancing of Ethernet links in Squid is very primitive because of
the information limitations Squid must work through. Load Balancing
Links is really a feature of the oeprating system you are using. It's
easily controlled at that level.
