///Clear the response.

/// Clear the server errors.

/// Create the route using RouteData (controller/action)

/// </summary>

private void RedirectToControllers(string control, string action)

{

    Response.Clear();

    Server.ClearError();

    var route = new RouteData();

    route.Values["controller"] = control;

    route.Values["action"] = action;

    IController controller = new AlertsController();

    var RequestCont = new RequestContext(new HttpContextWrapper(Context), route);

    controller.Execute(RequestCont);
