I have an ASP.NET MVC-application which I want deployable on both IIS6 and IIS7 and as we all know, IIS6 needs the ".mvc"-naming in the URL.

Will this code work to make sure it works on all IIS-versions? Without having to make special adjustments in code, global.asax or config-files for the different IIS-versions.

bool usingIntegratedPipeline = HttpRuntime.UsingIntegratedPipeline;

routes.MapRoute(
    "Default",
    usingIntegratedPipeline ?
        "{controller}/{action}/{id}" : "{controller}.mvc/{action}/{id}",
    new { controller = "Home", action = "Index", id = "" }
);

Update: Forgot to mention. No ISAPI. Hosted website, no control over the IIS-server.
