1) where does a local caching-nameserver get's it's information, about dns?

cat /etc/resolv.conf
nameserver 127.0.0.1
nameserver 8.8.8.8

so if i want information about foo.com, then if it's not cached, i ask the local caching-dns-server. it doesn't know, what is foo.com. so what does it do? it asks the second name server? the 8.8.8.8?

2) i just can't find where could i set that what is the largest cache size of the local dns server. how long does the local dns server stores the informations?


3) can i flush the dns cache? restart named?

thank you!
