Legacy Url Routing when application move from webform to MVC

// The legacy route class that exposes a RedirectActionNamepublic class LegacyRoute : Route{
    public LegacyRoute(string url, string redirectRuleName):base(url, new LegacyRouteHandler())
    {
        RedirectRuleName = redirectRuleName;
    }

    public string RedirectRuleName { get; set; }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        return null;
    }
}

 

/ The legacy route handler, used for getting the HttpHandler for the requestpublic class LegacyRouteHandler : IRouteHandler{
    public IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        return new LegacyHandler();
    }
}

// The legacy HttpHandler that handles the requestpublic class LegacyHandler : IHttpHandler{
    public void ProcessRequest(HttpContext context)
    {
        var requestContext = context.Request.RequestContext;
        string redirectActionName = ((LegacyRoute)requestContext.RouteData.Route).RedirectRuleName;

        var queryString = requestContext.HttpContext.Request.QueryString;
        foreach (var key in queryString.AllKeys)
        {
            requestContext.RouteData.Values.Add(key, queryString[key]);
        }

        VirtualPathData data = RouteTable.Routes.GetVirtualPath(requestContext, redirectActionName, requestContext.RouteData.Values);

        context.Response.Status = "301 Moved Permanently";
        context.Response.AppendHeader("Location", data.VirtualPath);
    }

    public bool IsReusable
    {
        get { return false; }
    }
} 

 And use rout mapping in global.as

routes.MapRoute(
    "Newroutname", // Route name
    "querystringParameter", // URL with parameters
    new { controller = "mycontroller", action = "actionname", id = UrlParameter.Optional } // Parameter defaults);
// redirect /oldurl to the Newroutname route.routes.Add("", new LegacyRoute("oldurl", "Newroutname"));
