If the rtt is less than the -# base time the rtt is set to a minimal value. -# -# ttl=N Specify a TTL to use when sending multicast ICP queries -# to this address. -# Only useful when sending to a multicast group. -# Because we don't accept ICP replies from random -# hosts, you must configure other group members as -# peers with the 'multicast-responder' option. -# -# no-delay To prevent access to this neighbor from influencing the -# delay pools. -# -# digest-url=URL Tell Squid to fetch the cache digest (if digests are -# enabled) for this host from the specified URL rather -# than the Squid default location. -# -# -# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ==== -# -# originserver Causes this parent to be contacted as an origin server. -# Meant to be used in accelerator setups when the peer -# is a web server. -# -# forceddomain=name -# Set the Host header of requests forwarded to this peer. -# Useful in accelerator setups where the server (peer) -# expects a certain domain name but clients may request -# others. ie example.com or www.example.com -# -# no-digest Disable request of cache digests. -# -# no-netdb-exchange -# Disables requesting ICMP RTT database (NetDB). -# -# -# ==== AUTHENTICATION OPTIONS ==== -# -# login=user:password -# If this is a personal/workgroup proxy and your parent -# requires proxy authentication. -# -# Note: The string can include URL escapes (i.e. %20 for -# spaces).
