MittelStufe 1Automatisiertiis

Beschreibung

The HttpOnly flag indicates to the user agent that the cookie must not be accessible by client-side script (i.e document.cookie). It is recommended that the httpOnlyCookies attribute be set to true. httpCookies httpOnlyCookies must be true in the root web.config and every site. PowerShell 5.1 with the WebAdministration module; run elevated.
