Functions

func Dial

func Dial(wrappedDial func(network, addr string) (net.Conn, error), maxEntries int) (func(network, addr string) (net.Conn, error), error)

Dial wraps the given dial function with Caching of DNS resolutions. When a hostname is found in the cache it will call the provided dial with the IP address instead of the hostname, so no DNS lookup need be performed. It will also cache DNS failures.

If the given wrappedDial is nil, net.Dial will be automatically used.
