How to write a Javascript frame buster

[ATC]

When authoring HTML pages, it sometimes becomes necessary or desirable to prevent the page from appearing inside (someone elses) frame set.

Include the following HTML code somewhere in the document. The script does not need additional configuration, and it can go in the BODY section if you want:

<SCRIPT LANGUAGE=JavaScript>
<!--

   top.location=self.document.location;
// -->
</SCRIPT>
