type DnsCacheConfig ¶
type DnsCacheConfig struct { // The name of the cache.

The // way this might work is a new lookup family which returns both IPv4 and IPv6 addresses, and // then configures a host to have a primary and fall back address. With this, we could very // likely build a "happy eyeballs" connection pool which would race the primary / fall back // address and return the one that wins.
