title: Busting out of an iframe using meta-refresh or javascript?
body: <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>
