Untrapping a Web Page
It happens sometimes that, for whatever reason, someone will display one of our pages in a frame on their website. Here is a method to un-trap the page and let the true URL show in the visitor's browser.
In the HEAD area, put this JavaScript:
<script type="text/javascript"><!-- if(top.location!=location){top.location.href=document.location.href;} //--></script>
The JavaScript checks to see if the page is the top document in the browser window. If it is not, it is in a frame. The JavaScript breaks out of the frame by reloading the web page as the top document in the window.
When the JavaScript is put into the HEAD area of the web page source code, it will run before the content loads into the browser.
