Eigenschaftenwert

true, wenn der Client das Cookie am Ende der aktuellen Sitzung verwerfen soll, andernfalls false. Der Standardwert ist false.

Hinweise

Wenn true, weist diese Eigenschaft die Clientanwendung an, das Cookie am Ende einer Sitzung nicht auf der Festplatte des Benutzers zu speichern.

Beispiel

Im folgenden Beispiel werden die Eigenschaften der Cookies angezeigt, die als Antwort zurückgeben wurden. Das vollständige Beispiel finden Sie unter dem Thema zur Cookie-Klasse.
