From the SEO standpoint it is nice to see urls in format which explains what is located on a page Let's have a look on such situation (it is just example) We need to display page about some user and decided to have such url template for that page: /user/{UserId}/{UserCountry}/{UserLogin}. And create for this purpose such model

public class UserUrlInfo{
   public int UserId{get;set;}
   public string UserCountry{get;set;}
   public string UserLogin{get;set;}
}

I want to create controller method where I pass UserUrlInfo object but not all required fields. Classic controller method for url template shown above is following

public ActionResult Index(int UserId, string UserCountry, string UserLogin){
    return View();
}

and we need to call it like that Html.ActionLink<UserController>(x=>Index(user.UserId, user.UserCountry, user.UserLogin), "See user page")

I want to create such controller method

public ActionResult Index(UserUrlInfo userInfo){
    return View();
}

and call it like that: Html.ActionLink<UserController>(x=>Index(user), "See user page")

Actually I works when we add one more route and point it to the same controller method, so routing will be: /user/{userInfo} /user/{UserId}/{UserCountry}/{UserLogin} In this situation routing engine gets string method of our model (need to override it) and it works ALMOST always. But sometimes it fails and show url like /page/?userInfo=/US/John

So my workaround does not always work properly. Does anybody know how to work with urls in such way?
