Tracking user's activity in MVC3

One way for tracking user's activity in MVC3:

1. I write class that implements the base class Action FilterAttribute, called
   UserTrackingActionFilterAttribute:

   public class UserTrackingActionFilterAttribute : ActionFilterAttribute
   {}

2. Override the method OnResultExecuting:

   public override void OnResultExecuting(ResultExecutingContext   context)
   {
       base.OnResultExecuting(context);
    }

3. In the method, I write the logic for store user's data. In my case, I have the repository (AccessesRepository) with a static method (WriteAccess), and I store ip address, url called, browser info:

    public override void OnResultExecuting(ResultExecutingContext context)
    {
            base.OnResultExecuting(context);
             new AccessesRepository().WriteAccess(
                               context.HttpContext.User.Identity.Name,                          HttpContext.Current.Request.UserHostAddress, HttpContext.Current.Request.Url.ToString(), HttpContext.Current.Request.UserAgent);
   
   }

4. Finally,I should register our filter into global.asax, into method Application_Start():

   protected void Application_Start()
    {
       AreaRegistration.RegisterAllAreas();
   
       GlobalFilters.Filters.Add(new UserTrackingActionFilterAttribute());
   
       RegisterGlobalFilters(GlobalFilters.Filters);
       RegisterRoutes(RouteTable.Routes);
   
    }

It's very simple.. and my english so poor!!!
