title: File download problem: filename with spaces truncated!
body: <p>While I am working on code to download file from server using : </p>
  
  <pre><code>Response.AddHeader("Content-Disposition", "attachment; filename=" + 
  Server.UrlPathEncode(Path.GetFileName(_Filename)));
  </code></pre>
  
  <p>The problem is while having spaces in the file name,  with this code the server split automatically while finding the first space!</p>
  
  <p>I'm hoping to know Why &amp; what is the solution for that? </p>
