For large responses, returning a `Response` directly is much faster than returning a dictionary.

This is because by default, FastAPI will inspect every item inside and make sure it is serializable as JSON, using the same [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank} explained in the tutorial. This is what allows you to return **arbitrary objects**, for example database models.

        assertEquals("/site1/search", result.getRoutingPath());

        // The header remains for subsequent tests due to static request handling
        // Different matching header added to same request
        request.addHeader("X-Forwarded-Host", "test.com");
        result = virtualHostHelper.getVirtualHostPath(page);
        assertEquals("/site1/search", result.getRoutingPath()); // Still site1 due to header precedence

        void testValueConsistency() {
            // Given: Same input value
            int inputValue = 1000;
            int expectedMasked = inputValue & 0xFF; // 232

            // When: Creating multiple NdrShort instances
            NdrShort ndrShort1 = new NdrShort(inputValue);
            NdrShort ndrShort2 = new NdrShort(inputValue);

            // Then: All should have same masked value
