[squid-users] Accelerating Multiple Servers

Greetings,

Trying to use Squid to both load share among and serve as an accelerator for
several web servers.
I can get it to accelerate one machine, I can get it to redirect requests
among several servers
in round-robin fashion, but I can't get it to cache requests made to ALL the
servers.
I've attached my squid.conf and redirect.pl file in
hopes someone can tell me how to correctly set up my squid.conf file.

The current set up only gets cache hits when the redirect sends requests to
kaui, 199.9.2.69

Thank you,
