MVC Dynamic Routes

Question

I would like to create dynamic urls that route to controller actions with an Id value. I've created the following route using a catch-all parameter

routes.MapRoute(
            "RouteName",                                                 
            "{id}/{*Url}",
            new { controller = "Controller", action = "Action", id = "" }
        );

This works as expected and allows me to use the following Urls:

"http://website.com/1/fake/url/path" (1 being the id that gets passed to the action method)

Does anyone know a way to achieve it this way instead without creating my own http module?:

"http://website.com/fake/url/path/1"

Thanks - Mark

That's a really difficult one, for me anyway.

Given the following route:

routes.MapRoute("Default", "{*token}", 
    new { controller = "Home", action = "Index", token = 0 });

Your controller and supporting classes would be something like this:

[HandleError]
public class HomeController : Controller
{
    public ActionResult Index([ModelBinder(typeof(IndexReqquestBinder))] IndexRequest request)
    {
        ViewData["Title"] = "Home Page";
        ViewData["Message"] = String.Format("We're looking at ID: {0}", request.ID);

        return View();
    }
}

public class IndexRequest
{
    public Int32 ID { get; set; }
    public IndexRequest(Int32 id)
    {
        this.ID = id;
    }
}

public class IndexReqquestBinder : IModelBinder
{
    public ModelBinderResult BindModel(ModelBindingContext bindingContext)
    {
        if ( null != bindingContext.RouteData.Values["token"] ) {
            foreach ( String v in bindingContext.RouteData.Values["token"].ToString().Split('/') ) {
                Int32 id = 0;
                if ( Int32.TryParse(v, out id) ) {
                    return new ModelBinderResult(new IndexRequest(id));
                }
            }

        }
        return new ModelBinderResult(new IndexRequest(0));
    }
}
