[squid-users] How can I use to squid servers ea for specific website?

Hello List.

I would like to know how I can use two squid servers to redirect traffic
for an especific page through the second squid server connected to a
different provider.

For ie:
                         squid2 ---- provider 1 (used for facebook.com
ONLY)
                             |
lan ---------------- |
                             |
                         squid1 ---- provider 2 (default server used for
everything except facebook)

I need to know how to use squid2 as a slave and what configuration do I
need on squid1 (master) in order for me to accomplish my task or the
rules need to be done with iptables?

Thanks for your time.
