title: Issue posting Form within iframe in Internet Explorer 11
body: <p>I have a web page embedded as a form within an iFrame.</p>
  
  <p>The web page posts back using the following javascript code triggered from an anchor tag</p>
  
  <pre><code>function GoToPdf(link) {
      var form = document.forms[0];
      form.action = link;
      form.target = "_blank";
      form.method = "Post";
      form.submit();
  }
  </code></pre>
  
  <p>The link passed is an .aspx page that retrieves JSON data passed in the request body and creates a PDF for download.</p>
  
  <p>The whole thing works fine on Chrome and Firefox but not on IE 11. If the web page is outside of an iFrame it also works on IE 11.</p>
  
  <p>In the iframe on IE 11 the page posts back to the .aspx page but the request body contains no data.</p>
  
  <p>Any ideas.</p>
  
  <p>Thanks</p>
  
  <p>Tim</p>
