[squid-users] questions/issues with balance_on_multiple_ip

i'm using squid as a reverse-proxy/accelerator in front of three apache
servers.

i'm trying to find a way to bind each visitor to a single apache server.

from the comments in squid.conf, it looks like balance_on_multiple_ip is
what i want:

# TAG: balance_on_multiple_ip
# Some load balancing servers based on round robin DNS have been
# found not to preserve user session state across requests
# to different IP addresses.
#
# By default Squid rotates IP's per request. By disabling
# this directive only connection failure triggers rotation.

i've disabled balance_on_multiple_ip, but it doesn't seem like squid's
behavior has changed.

am i mistaken about what this feature does?

is there anything else i need to do to get this feature to work?
(additional iptables conntrack rules or config?)

is there any way i can monitor squid to test how it is dealing with
sessions?

thank you!
