title: $_SERVER['HTTP_X_FILENAME'] undefined only on Go Daddy
body: <p>Hey there so I have sent in a support ticket to go daddy but they aren't being very helpful. In an admin panel for one of my client's websites there is an AJAX image uploader. Normally I don't work with Go Daddy and the script has always worked just fine with other hosts. However this client has forced me into dealing with Go Daddy's mess of a system and I am having trouble getting the AJAX image uploader to work. </p>
  
  <p>The problem seems to be that the <code>$_SERVER['HTTP_X_FILENAME']</code> is simply not defined, even when a file is posted to PHP using an HTTP request.</p>
  
  <p>In my PHP code I have the following line to grab the file name: </p>
  
  <pre><code>$fn = (isset($_SERVER['HTTP_X_FILENAME']) ? $_SERVER['HTTP_X_FILENAME'] : false);
  </code></pre>
  
  <p>And on Go Daddy it returns false. Also if I <code>print_r($_SERVER); HTTP_X_FILENAME</code> isn't even defined.</p>
  
  <p>I have checked permissions and everything has the correct permisssions. I have checked the error log and no error is being generated. I have checked the php.ini and file uploads is enabled with a 32mb max (way bigger than any file i'v tested with)</p>
  
  <p>I have no idea where to look now as my google searches have come up with nothing. (And server admin really isn't my forte)</p>
  
  <p>any help would be much appreciated.</p>
  
  <p>thanks!!</p>
