title: IFRAME makes src servlet execute twice on ipad safari
body: <p>I have an <code>iframe</code> which gets its content from a <code>servlet</code>. The problem is that the <code>servlet</code> doGet method gets executed twice when the page of the <code>iframe</code> is loaded. Here is the html:</p>
  
  <pre><code>&lt;div style="position: absolute;top: 135px;left:0px;overflow-y:scroll;overflow-x:scroll;width: 975px;height: 873px;" align="center"&gt;
      &lt;iframe src="documentviewer?docid=#{viewIncomingBean.connectedAttachment.id}" width="630px" height="873px" style="border: 1px solid black;"&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>this problem only show up when i run the application on <code>ipad</code> safari, it works fine on firefox</p>
  
  <p>Is there any way to prevent the double execution of the <code>servlet</code>?</p>
