URL Manipulation with RouteBase

2] For URL manipulation  that should ignore the very end extension in url. the extension can be: .html, .aspx, .php

/Home.html should go to Home Controller and 
/Home/index.aspx should go to Home Controller Index Action.

Implement Custom Base entry RouteBase

public class MyUrlRoute : RouteBase
{

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        //~/Account/LogOn
        //~/Home.aspx - Works fine
        //~/home/index.aspx  -Works Fine
        //http://localhost:57282/home/index/1/2/3 - Works fine
        //http://localhost:57282/Account/Register  http://localhost:57282/Account/LogOn - Works Fine

        string url = httpContext.Request.AppRelativeCurrentExecutionFilePath;

        //check null for URL
        const string defaultcontrollername  = "Home";
        string[] spliturl = url.Split("//".ToCharArray());
        string controllername = String.Empty;
        string actionname = "Index";



        if (spliturl.Length == 2) //for ~/home.aspx and ~/
        {
            if (String.IsNullOrEmpty(spliturl[1])) //TODO:  http://localhost:57282/ not working - to make it working
            {
                controllername = defaultcontrollername;
            }
            else
            {
                controllername = spliturl[1];
                if (controllername.Contains("."))
                {
                    controllername = controllername.Substring(0, controllername.LastIndexOf("."));
                }
            }
        }
        else if (spliturl.Length == 3) // For #/home/index.aspx and /home/about
        {
            controllername = spliturl[1];
            actionname = spliturl[2];
            if (actionname.Contains("."))
            {
                actionname = actionname.Substring(0, actionname.LastIndexOf("."));
            }
        }
        else //final block in final case sned it to Home Controller
        {
            controllername = defaultcontrollername;
        }


        RouteData rd = new RouteData(this, new MvcRouteHandler());
        rd.Values.Add("controller", controllername);
        rd.Values.Add("action", actionname);
        rd.Values.Add("url", url);
        return rd;
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        return null;
    }
and in global.aspx add below code.
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.Add(new MyUrlRoute()); // Add before your default Routes

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

    }
