I know you've said you want to do this in IIS, but if you can edit the Global.asax file in the application, you can do it this way.

protected void Application_BeginRequest(object sender, EventArgs e)
{
        #if !DEBUG
        string HTTPhost = Request.ServerVariables["HTTP_HOST"];

        string domainName = "test";

        //assuming that the app will only be reached via .COM or .NET
        string topLevel = HTTPhost.Split('.').LastOrDefault();

        //compare to make sure it only matches the root name with no trailing subdomain
        //or to redirect to secure url if unsecured
        if ( (!HTTPhost.Split('.').FirstOrDefault().Equals(domainName, StringComparison.InvariantCultureIgnoreCase) )
         || (!HttpContext.Current.Request.IsSecureConnection))
        {
            Response.RedirectPermanent(
              "https://"
              + domainName
              + '.'
              + topLevel
              + HttpContext.Current.Request.RawUrl);
            //RawUrl means any url information after the domain
        }
       #endif
}
