but you might want to omit them from the result if they were not actually stored.

For example, if you have models with many optional attributes in a NoSQL database, but you don't want to send very long JSON responses full of default values.

### Use the `response_model_exclude_unset` parameter { #use-the-response-model-exclude-unset-parameter }

// call Recycle() when the object is no longer needed.
// The recycler should handle nil pointers.
type Recycler interface {
	Recycle()
}

// MSS is a map[string]string that can be serialized.
// It is not very efficient, but it is only used for easy parameter passing.
type MSS map[string]string

// Get returns the value for the given key.
func (m *MSS) Get(key string) string {
	if m == nil {
		return ""
	}

        // Setting SSL socket factory to null should work
        request.sslSocketFactory(null);

        assertNotNull(request);
    }

    @Test
    public void testLongUrl() {
        // Test with very long URL
        StringBuilder longUrl = new StringBuilder("https://example.com/path");
        for (int i = 0; i < 100; i++) {
            longUrl.append("/segment").append(i);
        }

En este caso, el cliente verá un response *HTTP 500 Internal Server Error* como debería, dado que no estamos lanzando una `HTTPException` o similar, pero el servidor **no tendrá ningún registro** ni ninguna otra indicación de cuál fue el error. 😱
