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. Can be set globally using the CefSettings.PersistSessionCookies value. This value will be ignored if CachePath is empty or if it matches the CefSettings.CachePath value.

public bool PersistSessionCookies { get; set; }

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