// port "80" and "443" before displaying on the startup
// banner.  Returns a new list of API endpoints.

	if len(apiEndpoints) == 1 {

    @DisplayName("HTTP vs HTTPS Comparison Tests")
    class ProtocolComparisonTests {

        @Test
        @DisplayName("Should use different ports for HTTP and HTTPS")
        void testDifferentPorts() {
            // Given
            Handler httpsHandler = new Handler(null);

            // When
            int httpsPort = httpsHandler.getDefaultPort();

```sh
ufw allow 9000
```

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

```sh
ufw allow 9000:9010/tcp
```

### firewall-cmd

For hosts with firewall-cmd enabled (CentOS), you can use `firewall-cmd` command to allow traffic to specific ports. Use below commands to allow access to port 9000

        }
    }

    @Nested
    @DisplayName("HTTP vs HTTPS Comparison Tests")
    class ProtocolComparisonTests {

        @Test
        @DisplayName("Should use different ports for HTTP and HTTPS")
        void testDifferentPorts() {
            // Given
            Handler httpsHandler = new Handler();

            // When
            int httpsPort = httpsHandler.getDefaultPort();

So, all these are different origins:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

Even if they are all in `localhost`, they use different protocols or ports, so, they are different "origins".
