One problem has arisen and that is the need for all my customers to authenticate 3 times! Any ideas as to being able to reduce this to a single authentication?
The problem you are seeing is that Basic proxy authentication is per proxy. The browser won't send the same login+password to another proxy without first asking the user.
To solve this you need to either use Digest authentication with the same realm on all proxies (and hope the browsers handle this correctly), or use a DNS round-robin entry to distribute the clients among the caches and return only this DNS entry in proxy.pac. You could also set up the proxy.pac to statically select only one of the proxies for the duration of the session.
