title: Flex file upload issue io error #2038 over HTTPS
body: <p>Hi i have a flex file upload application over https it works fine on all IE browsers. 
  Recently a client with IE9 reported a complaint that she's not able to upload files.</p>
  
  <p>I can see the error generated is IO Error #2038.</p>
  
  <p>The adobe documentation says 2038 is File I/O Error.This error occurs when an application can't get file size, creation date or modification data using the FileReference API.</p>
  
  <p>Can some one help me point out what could be the issue here.
  All i can think of is browser issues like, browser cache, some new configuration in IE9 am unaware of or permission on the client directory.</p>
  
  <p>Help will be much appreciated.
  thanks</p>
