MVC: How to manage slahses in URL int the first route parameter

Question

I need to map two variables that could contain slashes, to a controller, in my ASP MVC application. Let\'s see this with an example.

Answer 1

Finally, based in the answer of Darin Dimitrov, I implemented the following custom route, that solves my problem:

public class RepositoryRoute : Route
{
    public RepositoryRoute(string name, string url, object defaults)
        : base(url, new RouteValueDictionary(defaults), new MvcRouteHandler())
    {
        string moduleUrl = url.Replace(
            REPOSITORY_PARAMETER, REPOSITORY_PARAMETER + MODULE_PARAMETER);
        mModuleRoute = new Route(
            moduleUrl, new RouteValueDictionary(defaults), new MvcRouteHandler());
    }

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        RouteData rd = mModuleRoute.GetRouteData(httpContext);

        if (rd == null)
            return base.GetRouteData(httpContext);

        if (!rd.Values.ContainsKey(MODULE))
            return rd;

        // set repository as repo/submodule format
        // if a submodule is present in the URL
        string repository = string.Format("{0}/{1}",
            rd.Values[REPOSITORY],
            rd.Values[MODULE]);

        rd.Values.Remove(MODULE);
        rd.Values[REPOSITORY] = repository;

        return rd;
    }

    Route mModuleRoute;

    const string REPOSITORY = "repository";
    const string MODULE = "module";

    const string REPOSITORY_PARAMETER = "{" + REPOSITORY + "}/"; // {repository}/
    const string MODULE_PARAMETER = "{" + MODULE + "}/"; // {module}/
}

Which is registered in the following way:

       routes.Add(new RepositoryRoute(
                        "Items",
                        "{repository}/Items/{*path}",
                        new { controller = "Items", action = "Index", path = "/" }
        ));

The route uses an internal route, that defines a module parameter, and if it's found, I concat it to the repository, and remove it. So mapping repository or repository/module is transparent.
