# Response – Statuscode ändern

Sie haben wahrscheinlich schon vorher gelesen, dass Sie einen Standard-[Response-Statuscode](../tutorial/response-status-code.md){.internal-link target=_blank} festlegen können.

In manchen Fällen müssen Sie jedoch einen anderen als den Standard-Statuscode zurückgeben.

## Anwendungsfall

Stellen Sie sich zum Beispiel vor, Sie möchten standardmäßig den HTTP-Statuscode „OK“ `200` zurückgeben.

   * order for a socket to be compatible the enabled cipher suites and protocols must intersect.
   *
   * For cipher suites, at least one of the [required cipher suites][cipherSuites] must match the
   * socket's enabled cipher suites. If there are no required cipher suites the socket must have at
   * least one cipher suite enabled.
   *
