[squid-users] LOOP DETECTED

I have 3 cache_peer devices I forward all my traffic thru from Squid. The
first two are McAfee E500 virus scanning devices and the 3rd is a
DansGuardian proxy running on the same squid box.

I have the cache_peer 127.0.0.1 going to DG for content scanning then back
to squid to be routed to internet on a subnet basis while other subnets go
thru e500b/e500c without going thru DG. I am now seeing in my cache.log
warnings like: WARNING: Forwarding loop detected for: . Is this because I
haven't specified a default parent? I am using cache_peer_access rules to
determine what subnets go to DG and what go to e500b/e500c. Below is my
cache_peer set up and the cache.log warning.

cache_peer e500b parent 80 0 no-query no-digest round-robin
cache_peer e500c parent 80 0 no-query no-digest round-robin
cache_peer 127.0.0.1 parent 8080 0 no-query no-digest
