Detailed Description

Although it would be possible for Squid to send and receive ICMP messages directly, we use an external process for two important reasons:
If you want to use Squid's ICMP features (highly recommended!) When USE_ICMP is defined, Squid will send ICMP pings to origin server sites. This information is used in numerous ways:
  • - Sent in ICP replies so neighbor caches know how close you are to the source.
  • - For finding the closest instance of a URN.
  • - With the 'test_reachability' option. Squid will return ICP_OP_MISS_NOFETCH for sites which it cannot ping.
