如何清除MVC中有关Custom HandleError属性的会话？

Question

I am creating my own custom HandleError attribute on MVC.

public class MVCError : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
         //Supposed to remove session here
    }
}

But it seems that I cannot use the Session to remove specific session on my website. Is this possible? Or do I need to clear my session on Global.asax file:

    protected void Application_Error()
    {
        Session.Remove("Check");
        Debug.WriteLine("An error has occurred.");
    }

You can clear use HttpContext.Current object HttpContext.Current.Session.Remove("Check");

public class MVCError : HandleErrorAttribute
    {
        public override void OnException(ExceptionContext filterContext)
        {
             //Supposed to remove session here
             HttpContext.Current.Session.Remove("Check");
        }
    }
