squid using more than one IP

[jeff donovan <donovan@xxxxxxxxxxxxxx>]

Greetings

currently i have a transparent squid, i was wondering if there is a  
way to have squid use more than 1 ip address or at least cycle through  
a pool of addresses when requesting a site.
I have a small block of IP's allocated, behind a firewall. can i have  
a single squid round robin somehow or is that an OS interface setting ?

any ideas ?
