MVC Authorization - multiple login pages

I think it is possible by creating a custom authorization filter:

public class CustomAuthorization : AuthorizeAttribute
{
    public string LoginPage { get; set; }

    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
        {
            filterContext.HttpContext.Response.Redirect(LoginPage);
        }
        base.OnAuthorization(filterContext);
    }
}

In your action:

[CustomAuthorization(LoginPage="~/Home/Login1")]
public ActionResult Search() 
{
  return View();
}

[CustomAuthorization(LoginPage="~/Home/Login2")]
public ActionResult Edit() 
{
  return View();
}
