Method 1

Use this code in global.asax

public static void RegisterRoutes(System.Web.Routing.RouteCollection routes)
    {
        routes.Add(new System.Web.Routing.Route("{language}/{*page}", new CustomRouteHandler()));
    }
void Application_Start(object sender, EventArgs e)
    {
        RegisterRoutes(System.Web.Routing.RouteTable.Routes);
    }
void Application_BeginRequest(object sender, EventArgs e)
    {
        string URL = HttpContext.Current.Request.Url.PathAndQuery;
        string language = TemplateControlExtension.Language;
        if (URL.ToLower() == "/default.aspx")
        {
            HttpContext.Current.Response.Redirect("/" + language + URL);
        }
    }

make a router handler class like this…

public class CustomRouteHandler : IRouteHandler
{
    public IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        string language = TemplateControlExtension.GetString(null, requestContext.RouteData.Values["language"]).ToLower();
        string page = TemplateControlExtension.GetString(null, requestContext.RouteData.Values["page"]).ToLower();

        if (string.IsNullOrEmpty(page))
        {
            HttpContext.Current.Response.Redirect("/" + language + "/default.aspx");
        }

        string VirtualPath = "~/" + page;

        if (language != null)
        {
            if (!VIPCultureInfo.CheckExistCulture(language))
            {
                HttpContext.Current.Response.Redirect("/" + SiteSettingManager.DefaultCultureLaunguage + "/default.aspx");
            }
            TemplateControlExtension.Language = language;
        }
        try
        {
            if (VirtualPath.Contains(".ashx"))
            {
                return (IHttpHandler)BuildManager.CreateInstanceFromVirtualPath(VirtualPath, typeof(IHttpHandler));
            }
            return BuildManager.CreateInstanceFromVirtualPath(VirtualPath, typeof(Page)) as IHttpHandler;
        }
        catch
        {
            return null;
        }
    }
}

By using this i hope your requirement has fulfill…..

Method 2

Probably the best way to do this is to have an initial page where he chooses the language he wants. Then the site loads a cookie to his browser indicating his language preference. In subsequent visits, your site reads the cookie and automatically takes him to his language preference.
