If you can allow the multiple views to share a single cache, one
possibility is to create a separate "localhost" view as the single
caching view and forward all recursive queries to that view:
view "localhost" {
match-clients { ::1; };
};
view "view1" {
match-clients { view1-clients; };
max-cache-ttl 0; //disable caching to save memory
zone "." {
type forward;
forwarders { ::1; };
forward only;
};
// add other authoritative zones if necessary
};
view "view2" {
match-clients { view2-clients; };
max-cache-ttl 0;
zone "." {
type forward;
forwarders { ::1; };
forward only;
};
// add other authoritative zones if necessary
};
....
