help with forwarding loop

Hi all,

I'm trying to configure two squid proxies to share the load using
CARP. This is the configuration file for each proxy:

--proxy1--
cache_peer proxy.lasaltech.com parent 3128 3130 carp-load-factor=0.6
cache_peer proxy-is.usls.edu parent 3128 3130 carp-load-factor=0.4
acl PEERS src proxy.lasaltech.com mercury.usls.edu
cache_peer_access proxy.lasaltech.com !PEERS
cache_peer_access proxy-is.usls.edu !PEERS

--proxy2--
cache_peer proxy.lasaltech.com parent 3128 3130 carp-load-factor=0.8
cache_peer proxy.usls.edu parent 3128 3130 carp-load-factor=0.2
acl PEERS src proxy.lasaltech.com hercules.usls.edu
cache_peer_access proxy.lasaltech.com !PEERS
cache_peer_access proxy.usls.edu !PEERS

But I still get forwarding loop errors.

Note: proxy-is.usls.edu is an alias for `mercury.usls.edu' and
`proxy.usls.edu' is an alias for `hercules.usls.edu'

--from cache.log--
Via: 1.1 hercules.usls.edu:3128 (Squid/2.3.STABLE4), 1.0 mercury.usls.edu:3128
X-Forwarded-For: 192.168.1.237, 192.168.1.3M
