title: Response.AddHeader not working in IE
body: <p>I have a problem when I use <code>Response.AddHeader</code>. Firefox and Chrome work fine (They show the popup and download the file), but not in IE, where it only opens a blank popup and not do anything like download a file or show a prompt. The popup title is "<code>-- webpage dialog</code>".</p>
  
  <p>My code is below:</p>
  
  <pre><code>byte[] bRpt = ExportReportYoStream(rptMain, ExportFormatType.Excel);
  Response.ClearHeaders();
  Response.Clear();
  Response.ContentType = "application/vnd.ms-excel";
  Response.AddHeader("content-disposition", "attachment;filename=Test Document.xls");
  Response.BinaryWrite(bRpt);
  Response.Flush();
  Response.End();
  </code></pre>
  
  <p>I have also tried many changes like:</p>
  
  <pre><code>Response.ContentType = "application/Save";
  Response.ContentType = "application/octet-stream";
  </code></pre>
  
  <p>and many more as I can find on the internet.</p>
