MVC Filter

    public class MyFilter : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            // The controller will be the controller you add the filter to. Or some base controller
            var controller = filterContext.Controller as YourController;

            // Execute controller action from filter. 
            controller.SomeControllerMethod();

            // Redirect to controller action
            filterContext.Result = new RedirectToRouteResult( new System.Web.Routing.RouteValueDictionary
            {
                {"controller", "mycontroller"},    
                {"action", "myaction"},
                {"querystring", "?hello=true"}
            });

            // Redirect to external url
            filterContext.Result = new RedirectResult(url);
        }
    }
