making URL lowercase. Any easy or builtin way?

Question

Is there any easy/builtin way to make URL in lowercase for MVC3.

I have code that could do it but looking something simple to implement.

 routes.MapRouteLowercase(                 "Default", // Route name                 "{controller}/{action}/{id}", // URL with parameters                 new { controller = "Home", action = "index", id = UrlParameter.Optional } // Parameter defaults             );  public class LowercaseRoute : Route     {         public LowercaseRoute(string url, IRouteHandler routeHandler)             : base(url, routeHandler)         {         }          public LowercaseRoute(string url, RouteValueDictionary defaults, IRouteHandler routeHandler)             : base(url, defaults, routeHandler)         {         }          public LowercaseRoute(string url, RouteValueDictionary defaults, RouteValueDictionary constraints, IRouteHandler routeHandler)             : base(url, defaults, constraints, routeHandler)         {         }          public LowercaseRoute(string url, RouteValueDictionary defaults, RouteValueDictionary constraints, RouteValueDictionary dataTokens, IRouteHandler routeHandler)             : base(url, defaults, constraints, dataTokens, routeHandler)         {         }          public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)         {             VirtualPathData path = base.GetVirtualPath(requestContext, values);              if (path != null)             {                 path.VirtualPath = path.VirtualPath.ToLowerInvariant();             }              return path;         }     }     public static class RouteCollectionExtensions     {         public static Route MapRouteLowercase(this RouteCollection routes, string name, string url)         {             return routes.MapRouteLowercase(name, url, null /* defaults */, (object)null /* constraints */);         }          public static Route MapRouteLowercase(this RouteCollection routes, string name, string url, object defaults)         {             return routes.MapRouteLowercase(name, url, defaults, (object)null /* constraints */);         }          public static Route MapRouteLowercase(this RouteCollection routes, string name, string url, object defaults, object constraints)         {             return routes.MapRouteLowercase(name, url, defaults, constraints, null /* namespaces */);         }          public static Route MapRouteLowercase(this RouteCollection routes, string name, string url, string[] namespaces)         {             return routes.MapRouteLowercase(name, url, null /* defaults */, null /* constraints */, namespaces);         }          public static Route MapRouteLowercase(this RouteCollection routes, string name, string url, object defaults, string[] namespaces)         {             return routes.MapRouteLowercase(name, url, defaults, null /* constraints */, namespaces);         }          public static Route MapRouteLowercase(this RouteCollection routes, string name, string url, object defaults, object constraints, string[] namespaces)         {             if (routes == null)             {                 throw new ArgumentNullException("routes");             }             if (url == null)             {                 throw new ArgumentNullException("url");             }              Route route = new LowercaseRoute(url, new MvcRouteHandler())             {                 Defaults = new RouteValueDictionary(defaults),                 Constraints = new RouteValueDictionary(constraints),                 DataTokens = new RouteValueDictionary()             };              if ((namespaces != null) && (namespaces.Length > 0))             {                 route.DataTokens["Namespaces"] = namespaces;             }              routes.Add(name, route);              return route;         }          public static Route MapRouteLowercase(this AreaRegistrationContext context, string name, string url)         {             return context.MapRouteLowercase(name, url, (object)null /* defaults */);         }          public static Route MapRouteLowercase(this AreaRegistrationContext context, string name, string url, object defaults)         {             return context.MapRouteLowercase(name, url, defaults, (object)null /* constraints */);

        }          public static Route MapRouteLowercase(this AreaRegistrationContext context, string name, string url, object defaults, string[] namespaces)         {             return context.MapRouteLowercase(name, url, defaults, null /* constraints */, namespaces);         }          public static Route MapRouteLowercase(this AreaRegistrationContext context, string name, string url, object defaults, object constraints, string[] namespaces)         {             if (namespaces == null && context.Namespaces != null)             {                 namespaces = context.Namespaces.ToArray();             }              Route route = context.Routes.MapRouteLowercase(name, url, defaults, constraints, namespaces);             route.DataTokens["area"] = context.AreaName;              // disabling the namespace lookup fallback mechanism keeps this areas from accidentally picking up             // controllers belonging to other areas             bool useNamespaceFallback = (namespaces == null || namespaces.Length == 0);

I've just noticed that there is a new property in .NET Framework 4.5. Works great! RouteCollection.LowercaseUrls

Set LowercaseUrls to true

public static void RegisterRoutes(RouteCollection routes) {     routes.LowercaseUrls = true;     ... } 

Create a link

@Html.ActionLink("Log in", "Login", "Account") 

That will create awesome, lowercase url :)

<a href="/account/login">Log in</a>
