Redirect using flash detection

1

I am installing the flash detection kit and everything works great except when flash detects NO flash plug-in.

  } else {  // flash is too old or we can't detect the plugin
    var alternateContent = 'Alternate HTML content should be placed here.'
      + 'This content requires the Macromedia Flash Player.'
       + '<a href=http://www.macromedia.com/go/getflash/>Get Flash</a>';
    document.write(alternateContent);  // insert non-flash content
  }

I need to redirect from here to a html page.

Help?
