If we want to use a customized handler, we can create a type that implements the http.Handler interface. The http.Handler interface has one method, ServeHTTP, which has the following signature:19type Handler interface {20 ServeHTTP(ResponseWriter, *Request)21}22type ResponseWriter interface {23 Write([]byte) (int, error)24}
