title: input type="file" - temp files deleted with post-redirect-get
body: <p>I have a form where I allow the user to upload files. I just changed the post processing to a post-redirect-get since the user enters other information as well. I noticed that the global $_FILE is visible to the redirect.php but is lost after redirecting back to the input form. I attempted to save the $_FILE array, but it appears that the temp files are removed with the post-redirect-get. Is there any way to tell the server to preserve the temp files when leaving the redirect.php so I can process them when I see fit? Thanks in advance.</p>
  
  <p>User Form:</p>
  
  <pre><code>&lt;input type="file" name="file[]" id="userfiles" size='1px' multiple onChange="makeFileList();" /&gt;
  </code></pre>
  
  <p>Redirect File:</p>
  
  <pre><code>if (isset($_FILES)){
      $_SESSION['post-files'] = $_FILES;
  }
  header("Location: /back/to/input/form.php");
  </code></pre>
