Eğer web.config veya app.config dosyasında useUnsafeHeaderParsing özniteliği ayarlamanız gerekir. Değeri dinamik olarak çalışma zamanında değiştirmek isterseniz, değer System.Net.Configuration.SettingsSectionInternal
örneğinde gömülü ve herkese açık olarak erişilemediğinden yansıma başvurmanız gerekir. İşte
