What about this excerpt from "standard squid configuration
file"? It describes very clearly what you're saying / asking. BTW,
version 1.1.x. Regards ...
# TAG: source_ping
# If source_ping is enabled, then squid will include the source
# provider site in its selection algorithm. This is accomplished
# by sending ICP "HIT" packets to the UDP echo port of the source
# host. Note that using source_ping may send a fair amount of UDP
# traffic out on the Internet and may irritate paranoid network
# administrators.
#
# Note that source_ping is incompatible with inside_firewall.
# For hosts beyond the firewall, source_ping packets will never
# be sent.
#
# By default, source_ping is off.
