title: PrimeFaces fileUpload doesn't work on IE<=9
body: <p>The problem occurs only in IE&lt;=9. Everywhere else fileupload works perfectly.</p>
  
  <p>I'm using PrimeFaces version: 3.4.2.
  Upgrading to 4.0 doesn't change anything.</p>
  
  <p>I've copied code from: <a href="http://www.primefaces.org/showcase/ui/fileUploadAuto.jsf" rel="nofollow noreferrer">PrimeFaces FileUpload demo</a></p>
  
  <pre><code>&lt;h:form&gt;
  
              &lt;p:fileUpload fileUploadListener="#{fileUploadBean.listener}"
                  mode="advanced" update="messages" auto="true" sizeLimit="100000"
                  allowTypes="/(\.|\/)(gif|jpe?g|png)$/" /&gt;
  
              &lt;p:growl id="messages" showDetail="true" /&gt;
  
          &lt;/h:form&gt;
  </code></pre>
  
  <p>I've even defined:</p>
  
  <pre><code>&lt;meta http-equiv="X-UA-Compatible" content="IE=8" /&gt;
  </code></pre>
  
  <p>On my page it's not working but on <a href="http://www.primefaces.org/showcase/ui/fileUploadAuto.jsf" rel="nofollow noreferrer">FileUpload demo</a> page it's suprisingly working.</p>
  
  <p>I've noticed this strange behaviour on IE &lt;= 9 (Content-Length is 0 and Content-Type is not present - why?):</p>

  <p>But on PrimeFaces page there is (the same browser - IE8/9):</p>

  <p>I've also tried to set <code>enctype</code> to <code>multipart/form-data</code> and (like on PrimeFaces demo page) <code>application/x-www-form-urlencoded</code> (which is default)</p>
  
  <p>What can I do to get this to work?</p>
