Stub files and iframe busters
iframe busters or stub files are usually used in conjunction with Flash creatives that are served within an ad slot that is implemented in an iframe.
If your website implements its tags in iframes, you may find that certain creatives, such as Flash creatives, do not show and the backup GIF file is being served instead. If this is the case, you may need to upload an "iframe buster" or stub file onto your web server. These files are provided by 3rd-party ad servers and custom creative vendors. Your webmaster will normally upload these files to the following location:
www.example.com is your website root and
vendorname is the vendor whose creative you are attempting to traffic in an iframe.

DARTIframe.html file into
