title: jQuery file upload stuck in pending state with IE10, zero byte file
body: <p>I'm using this jQuery plug-in and seeing the same results on my website as I can reproduce on this demo:</p>
  
  <p><a href="http://blueimp.github.io/jQuery-File-Upload/">http://blueimp.github.io/jQuery-File-Upload/</a></p>
  
  <p>Even though the demo says "Upload server currently unavailable" you can still recreate the issue by going to the demo and trying to upload a zero byte file (must have a JPG, GIF or PNG extension since that is all they allow).</p>
  
  <p>In FireFox and Chrome you will see it attempts to POST the zero byte file.  In IE10, if you view the network tab in the developer tools, you will see an XMLHTTPRequest object stuck in "pending" state.  If you upload a file of non-zero size in IE10, you will also see it POST the data.</p>
  
  <p>I searched and found only a couple other people complaining about issues with zero byte files in IE10.  They are not using the same jQuery plug-in as me, so I think it is a general IE10 issue.  Also, the only answer I have found so far is to not allow users to upload zero byte files.  I would like to support zero byte files if possible, they have some usage in my application and I use them myself from time to time, so who am I to call my users crazy for wanting this feature.</p>
  
  <p><strong>What are my options?</strong></p>
