    void set (int value);
}

/** @property */
public int get_MaximumAutomaticRedirections ()

/** @property */
public void set_MaximumAutomaticRedirections (int value)

public function get MaximumAutomaticRedirections () : int

public function set MaximumAutomaticRedirections (value : int)

Eigenschaftenwert

Die maximale Anzahl von Umleitungsantworten, denen die Anforderung folgt. Der Standardwert ist 50.

Ausnahmen

Ausnahmetyp Bedingung

ArgumentException

Der Wert wird auf 0 oder weniger festgelegt.

Hinweise

Die MaximumAutomaticRedirections-Eigenschaft legt die maximale Anzahl von Umleitungen fest, denen die Anforderung folgen soll, wenn die AllowAutoRedirect-Eigenschaft true ist.
