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.
What means "not available" ??
If proxy p1 is "not available", usually the browser cannot connect to it or a request times out.
With a no-connect error, a browser does failover to the second proxy...
Just checking: p1 and p2 are parent proxies and s1,s2,s3 the proxies that the serve the browser requests?
If yes, shouldn't the PAC code return "PROXY s1:8080; PROXY s2:8080; PROXY s3:8080" ?

I am not sure, if turning off the error massages is an option?
Kind regards
