From ipcache.c;
if (ttl == 0 || ttl > Config.positiveDnsTtl)
ttl = Config.positiveDnsTtl;
if (ttl < Config.negativeDnsTtl)
ttl = Config.negativeDnsTtl;
i->expires = squid_curtime + ttl;
As I read this, if the TTL from an upstream resolver happens to be
'0', it changes it to whatever positive_dns_ttl is -- even though
that also acts as a ceiling for DNS TTLs.
The problem is that this plays havoc with DNS-based load balancers,
which will be '0' more often than other DNS entries by nature. Any
chance of either;
a) having the ttl == 0 test taken out
b) having the default if it is 0 separated out to a separate config
?
