The better approach would be to implement a custom ActionFilterAttribute and override the OnActionExecuting method to handle the logic and then just decorate your actions with the attribute.

public class CheckCookieAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // Check your cookie and handle the redirect here, otherwise, do nothing
        // You can get to your cookie through the filterContext parameter
    }
}

public class ActionController : Controller
{
    [CheckCookie]
    public ActionResult GetFoo()
    {
        return View();
    }
}

Hope this helps.
