To persist session cookies (cookies without an expiry date or validity interval) by default when using the global cookie manager set this value to true. Session cookies are generally intended to be transient and most Web browsers do not persist them. A CachePath value must also be specified to enable this feature. Also configurable using the "persist-session-cookies" command-line switch. Can be overridden for individual RequestContext instances via the RequestContextSettings.PersistSessionCookies value.

public bool PersistSessionCookies { get; set; }

public:
property bool PersistSessionCookies {
	bool get ();
	void set (bool value);
}
