I have a squid-A for my LAN, which forwards all http-traffic to a

squid-B using simple config:

cache_peer x.x.x.x parent yyyy 0 no-query no-digest no-netdb-exchange
......
never_direct allow all
But in case, the parent (squid-B) is not reachable, the clients
accessing
squid-A simply hang,
and in cache.log for squid-A I see
TCP connection to x.x.x.x/yyy failed
What would be the simplest method to set up an automatic backup, either
another parent (preferred) OR just to have a direct connection from
squid-A
?
In case of backup parent, it should ONLY be used in case squid-B fails.
The simplest way is to configure two parents:
cache_peer x.x.x.x parent yyyy 0 no-query no-digest no-netdb-exchange
default
cache_peer y.y.y.y parent zzzz 0 no-query no-digest no-netdb-exchange
The first will be used unless it goes down.
NP: You may have noticed the selection in access.log is called
FIRSTUP_PARENT as in "use the first available from list of parent
cache_peer's".
