Then your Squid needs an upgrade. The config file indicates it is for
3.5.20. But Squid-3 '-k parse' will absolutely complain when obsolete
Squid-2 directives are passed to them. Your config file contains at
least 3 such obsolete directives (no_cache).

It also uses QUERY ACL before defining what QUERY is.

Please define "effectively distribute" ?

You asked how to do "load balancing". The URL I referenced already
covers all the ways Squid can load balance. *Which* one is "effective"
depends on what you want to happen.

Your config file shows someone halfway through testing whether a
particular client->squid->proxy->Internet pathway works. Which is fine,
actually a good way to go about the change. One step at a time.

For info on the pieces needed for creating cache hierarchies see the top
two sections of <http://wiki.squid-cache.org/Features/CacheHierarchy>.
