What are iframe busters – stub files?

Iframe busters or stub files are commonly utilized by third-party vendors in conjunction with Flash creatives such as media rich advertisements that are served within an ad slot implemented in an iframe. You may have noticed visitors to your website visit a page on your website that does not exist ending in /eyeblaster/addineyev2.html, /doubleclick/DARTIframe.html, /atlas/atlas_rm.htm, and many others. These pages often results in a 404 error.
