It only works the other way. When a request is forwarded by a Squid it
adds it's ID to the Via header. If it sees a request which according to
the Via header has already been here then this warning is logged and Squid
will be very reluctant about using further peers in resolving this

Other than cluttering your access.log this message should not cause any
noticeable harm.
