Localizing URL’s

We can localize our URL’s using an AttribtueRouting translation provider. A translation provider is useful to work against resx files, databases, etc. To create our own, simply extend

routes.MapAttributeRoutes(myConfig =>
{
myConfig.AddTranslationProvider(new MyCustomTranslationProvider());
});

Route Convention Attribute Attribute

public class MyRouteConventionAttribute : RouteConventionAttributeBase
{
public override IEnumerable
GetRouteAttributes(MethodInfo actionMethod)
{
// TODO: Yield IRouteAttributes (GET/POST/PUT/DELETE/Route).
}
}

Subdomain Routing

Wc can map our ASP.NET MVC areas to subdomains by using the Subdomain property of the RouteAreaAttribute. Doing so ensures that the routes for the area are matched only when requests are made to the specified subdomain. Here’s how:

[RouteArea(“Users”, Subdomain = “users”)]
public class SubdomainController : Controller
{
[GET(“”)]
public ActionResult Index() { /* … */ }
}
