Hi Thomas

You cannot. The earliest notification you can use for it, is this one - this should do the trick:

[Dynamicweb.Extensibility.Notifications.Subscribe(Dynamicweb.Notifications.Standard.Page.DeviceDetected)]
    public class DeviceDetectedObserver : Dynamicweb.Extensibility.Notifications.NotificationSubscriber
    {

        public override void OnNotify(string notification, Dynamicweb.Extensibility.Notifications.NotificationArgs args)
        {
            if (args == null)
            {
                return;
            }

            var loadedArgs = (Dynamicweb.Notifications.Standard.Page.DeviceDetectedArgs)args;
            if (!string.IsNullOrEmpty(Context.Current.Request.QueryString["contenttype"]))
            {
                var contentType = Context.Current.Request.QueryString["contenttype"];
                //validate content type
                loadedArgs.PageView.Redirect = false;
                loadedArgs.PageView.Page.ContentType = contentType;
            }
        }

    }
