The result will be discarded.

### Typed handlers

Typed handlers are handlers that have a specific type for the request and response payloads.
These must provide `msgp` serialization and deserialization.

In the examples we use a `MSS` type, which is a `map[string]string` that is `msgp` serializable.

```go
    handler := func(request *grid.MSS) (*grid.MSS, *grid.RemoteErr) {

}

// corsHandler handler for CORS (Cross Origin Resource Sharing)
func corsHandler(handler http.Handler) http.Handler {
	commonS3Headers := []string{
		xhttp.Date,
		xhttp.ETag,
		xhttp.ServerInfo,
		xhttp.Connection,
		xhttp.AcceptRanges,
		xhttp.ContentRange,
		xhttp.ContentEncoding,
		xhttp.ContentLength,
		xhttp.ContentType,

        }
    }

    // Simple collaborator to demonstrate interaction verification with Mockito
    interface Handler {
        void handle(int code, String message);
    }

    @Mock
    Handler handler;

    @Test
    @DisplayName("Interaction: handler called with each code/message pair")
    void interaction_with_mock_handler_is_as_expected() {

func (m *Manager) AddToMux(router *mux.Router, authReq func(r *http.Request) error) {
	router.Handle(m.routePath, m.Handler(authReq))
}

// Handler returns a handler that can be used to serve grid requests.
// This should be connected on RoutePath to the main server.
func (m *Manager) Handler(authReq func(r *http.Request) error) http.HandlerFunc {
	return func(w http.ResponseWriter, req *http.Request) {

        System.clearProperty("java.protocol.handler.pkgs");
        SingletonContext.registerSmbURLHandler();
        assertEquals("jcifs", System.getProperty("java.protocol.handler.pkgs"));
    }

    @Test
    void testRegisterSmbURLHandlerWhenPkgsDoesNotContainJcifs() {
        // Test registerSmbURLHandler when java.protocol.handler.pkgs does not contain "jcifs"

  private TestLogHandler handler;
  private final TearDownStack stack = new TearDownStack();

  @Override
  protected void setUp() throws Exception {
    super.setUp();

    handler = new TestLogHandler();

    // You could also apply it higher up the Logger hierarchy than this
    ExampleClassUnderTest.logger.addHandler(handler);

            MavenProject project, String artifactType, String artifactClassifier, File artifactFile) {
        ArtifactHandler handler = null;

        if (artifactType != null) {
            handler = artifactHandlerManager.getArtifactHandler(artifactType);
        }

        if (handler == null) {
            handler = artifactHandlerManager.getArtifactHandler("jar");
        }

	nonLoopBackIP := getNonLoopBackIP(t)
	handler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		fmt.Fprintf(w, "Hello, world")
	})

	testCases := []struct {
		addrs   []string
		handler http.Handler
		certFn  certs.GetCertificateFunc
