| If you're running on Linux, there is a trick which can balance
| between 2 squid instances running on the same box, discriminating between
| the two depending on the client IP address.
| Run the second instance on some other http_port (i.e. 4128) and add this
| iptables rule:
|
| iptables -t nat -A PREROUTING -s 0.0.0.0/0.0.0.1 -p tcp \
|          --destination-port 3128 -j REDIRECT --to-ports 4128
|
|
| More instances (in powers of 2) should be possible using similar tricks.
