<p>I basically have a page which shows a "processing" screen which has been flushed to the browser.  Later on I need to redirect this page, currently we use meta refresh and this normally works fine.  </p>

<p>With a new payment system, which includes 3D secure, we potentially end up within an iframe being directed back to our site from a third party.</p>

<p>I need to be able to redirect from this page, either using javascript or meta-refresh, and bust out of the iframe if it exists.</p>

<p>Cheers!</p>

<p>(I have done busting out of iframes before but can't find my old code and a google search was useless, thought it was the perfect time to try Stackoverflow out!)</p>

So I added the following to my redirected pages.  Luckily they have nothing posted at them so can be simply redirected.  Also the use of javascript is ok as it is required to get to that point in the site.
```
```
<script type="text/javascript" language="javascript">
    if (top.frames.length>0)
    setTimeout("top.location = window.location;",100);
</script>
```
```
