    `DurationUnit` which was a typealias in 1.5.x.
 *  Upgrade: [Okio 3.2.0][okio_3_2_0].


## Version 5.0.0-alpha.9

_2022-06-16_

 *  New: Enforce label length limits in URLs. `HttpUrl` now rejects URLs whose domains aren't valid.
    This includes overly-long domain names (longer than 253 characters), overly-long labels (more
    than 63 characters between dots), and empty labels.

Content-Type: text/plain
Content-Length: 1759
Connection: keep-alive
```

We can see that we were redirected because `response.request().url()` is different from `request.url()`. The two log statements log two different URLs.

### Network Interceptors

Registering a network interceptor is quite similar. Call `addNetworkInterceptor()` instead of `addInterceptor()`:

```java
OkHttpClient client = new OkHttpClient.Builder()

    }

    private static final Logger log = LoggerFactory.getLogger(Config.class);

    /**
     * This static method registers the SMB URL protocol handler which is
     * required to use SMB URLs with the <code>java.net.URL</code> class. If this
     * method is not called before attempting to create an SMB URL with the
     * URL class the following exception will occur:
     * <blockquote>
     *
     * <pre>

Die meisten dieser Einstellungen sind variabel (können sich ändern), wie z. B. Datenbank-URLs. Und vieles könnten schützenswerte, geheime Daten sein.

Aus diesem Grund werden diese üblicherweise in Umgebungsvariablen bereitgestellt, die von der Anwendung gelesen werden.

## Umgebungsvariablen

/// tip | Tipp

success.upload_design_file = {0} aktualisiert.

            .writeUtf8(ByteString.of(utf8[i]).hex().uppercase())
        }
        return percentEncoded.readUtf8()
      }
    },

    /** URLs that contain this character in this component are invalid.  */
    FORBIDDEN,

    /** Hostnames that contain this character are encoded with punycode.  */
    PUNYCODE,

La mayoría de estas configuraciones son variables (pueden cambiar), como las URLs de bases de datos. Y muchas podrían ser sensibles, como los secretos.

Por esta razón, es común proporcionarlas en variables de entorno que son leídas por la aplicación.
