Name
test_reachability
Synopsis
When you enable this directive, Squid looks at its netdb
database while processing ICP queries. If Squid normally returns
ICP_MISS
, but the origin server
isn’t in the database or doesn’t respond to ICMP pings, it returns
ICP_MISS_NOFETCH
instead. The
ICP_MISS_NOFETCH
reply signals the
neighbor cache that Squid might not be able to communicate with the
origin server.
