Hi,

I would like to setup a proxy.pac which would be able to handle the
following situations, could someone tell me how should I start?
Thanks!

1) 1st proxy URL fails and the second one is OK.-1st is a dummy
proxy, second one is valid.
2) 1st proxy URL fails and the second one is Direct-1st is a
dummy proxy, then it should go direct.
3) 1st and 2nd proxy URL fail, 3rd is OK---1st and 2nd are dummy,
3rd is valid proxy
