title: Redirect Parent of iframe on different domain - alternative logic
body: <p>I know similar questions have been asked before, but I was wondering if anyone could help find a solution to a particular problem:</p>
  
  <p>I have a form that I'd like to embed in a few different web sites, on different domains.  This form  needs to redirect to PayPal.  The plan was to embed this form in an iframe, making it easy to update etc, plus minimal code to embed.  However, due to same origin policy I cannot use <code>parent.location.href = "http://PaypalPaymentAddress.com";</code> to redirect the form.  I don't want to process the payment in the frame (Paypal anyway forbids this)...</p>
  
  <p>The only way around this I can think of is having a script run and render the form into the parent page, calling a web service or so to get the HTML, but that would obviously be a lot of work!</p>
  
  <p>Any ideas how I might set this up to get it working?</p>
