Tag Name mcast_icp_query_timeout (msecs)
Usage mcast_icp_query_timeout milliseconds

Description
For Multicast peers, Squid regularly sends out ICP “probes” to count how many other peers are listening on the given multicast address. This value specifies how long Squid should wait to count all the replies.

When Squid sends out a multicast query, it will wait at most mcast_icp_query_timeout seconds (it’s perfectly possible that one day a peer will be on the moon: and it would probably be a bad idea to peer with that cache seriously, unless it was a parent for the Mars top-level domain.) It’s unlikely that you will want to increase this value, but you may wish to drop it, so that only reasonably speedy replies are considered.

Default mcast_icp_query_timeout 2000

Caution
Do NOT use this option to always use a fixed (instead of a dynamic) timeout value.
