wpad does a good job.
I am not sure how it balances but the failover works fine.

So, what you can do is divide the client IP address range in
3 segments and via the PAC file make a decision which
proxy (S_i) will be the primary proxy; the browser wil only
use the secondary proxy when the first one is not available.
I checked this out, but it did not work, because when the PAC-File
returns:
"PROXY p1:8080; PROXY p2:8080";
and the parent-proxy of p1 is not available, p1 returns a error-message
("parent not available") and the browser will not failover to p2,
because the request yield HTML and everything seems to be fine for the
browser.
I am not sure, if turning off the error massages is an option?
Kind regards
Thomas
