You can use proxy.pac to provide failover and load balancing only when 
multiple squids are all accessible by the clients.

Additionaly for all the clients without auomatic configuration or when 
you have a proxy which is only reachable by other proxies (firewalls 
etc) you could implement a parent-child relationships. You may need to 
adjust how object are retrieved. Have a look at always_direct & 
never_direct after specifying a parent.

We use a similar approach: Nearly everything is fetched through a 
parent. When the parent goes down, everything is fetched direct. I have 
never tried it the other way round but I remember this question on the 
list somehow. Check the archives.
