Need more info for dns_nameservers in Squid 2.6 version

["Jonnalagadda, Venkata" <Venkata.Jonnalagadda@xxxxxxx>]

Need more info on dns_nameservers

Question :

1) Whether dns_nameservers has round-robin fashion during failure case ?

Example : dns_nameservers IP1 IP2 IP3

Here, if IP1 failed then squid will try for IP2 ? if further IP2 failed
then squid will try for IP3 ?


Thanks & Regards
