Language dependent routes in ASP.NET MVC

Has anyone had any experienced with making language dependent routes with ASP.NET MVC? What I would like to do is have localized url's to improve SEO. So for example http://mysite.com/products/cars would map to the same controller/action as http://mysite.com/produkter/bilar?

I have tried browsing around a bit, but I could not find anything similar to this. I'm not even convinced it is really such a good idea, but I would imagine that it would help SEO when users are doing searches in their own language. I would imagine this would take some customization of the mvc route engine.

Edit: Mato definitely has the best solution so far, I would like to see a Custom RouteHandler solution though for reference.

I won't recommend a Regex based approach because it will be error-prone, other than requiring a strong level of manual customization of all the available URL patterns (wich can be a real pain for non-trivial websites).

Just as @Runeborg said, I strongly recommend a more automated way of doing the job. For MVC 5 (and <) web applications I always use the following one, which I found to be the most versatile one among those I've tried in the latest years.

You basically need to implement three things:

  • A multi-language aware route to handle incoming URLs (if you're using MVC5 or above you could also go for Attribute-based routing instead, but I still prefer to use a global rule to handle this).
  • A LocalizationAttribute to handle these kinds of multi-language requests.
  • An helper method to generate these URLs within your application (Html.ActionLink and/or Url.Action extension methods).

See this answer for further details and code samples.

For additional info and further samples on this topic you can also read this blog post that I wrote on this topic.

You could implement an own controller factory class which translates the controller name before initializing it. You could for example store the translations in a resource file or in a DB. The easiest way to do this is to inherit from DefaultControllerFactory and to overwrite the CreateController function.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace System.Web.Mvc
{
    class CustomControllerFactory : DefaultControllerFactory
    {
        public override IController CreateController(System.Web.Routing.RequestContext requestContext, string controllerName)
        {
            /**
             * here comes your code for translating the controller name 
             **/

            return base.CreateController(requestContext, controllerName);
        }
    }
}

The last step would be to register your controller factory implementation when the application starts (in the Global.asax).

namespace MyApplication
{
    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            ControllerBuilder.Current.SetControllerFactory(typeof(CustomControllerFactory));
        }
    }
}

You could use regular expression routes (http://iridescence.no/post/Defining-Routes-using-Regular-Expressions-in-ASPNET-MVC.aspx), and then do something like

routes.Add(new RegexRoute(@"^(Products|Produkter)$", new MvcRouteHandler())
{
    Defaults = new RouteValueDictionary(new { controller = "Products"  })
});

One thing with SEO is, if a search engine finds two identical documents on two different links, it may reduce page rank for one of the pages. You need then to translate the page content as well.
