TAG NAME query_icmp

Description Enabling this option, makes Squid to ask your peers to include ICMP data in their ICP replies
Build Option
 –enable-icmp
Usage
 query_icmp on|off
Default
 query_icmp off
Synopsis
If your peer has configured Squid (during compilation) with ‘–enable-icmp’ then that peer will send ICMP pings to origin server sites of the URLs it receives.  If you enable this option then the ICP replies from that peer will include the ICMP data (if available). Then, when choosing a parent cache, Squid will choose the parent with the minimal RTT to the origin server.  When this happens, the hierarchy field of the access.log will be “CLOSEST_PARENT_MISS”.  This option is off by default.

Arguments

on/off
 Enable or disable this option
