title: Export string to CSV not working
body: <p>I am trying to download a string into CSV file with the following code:</p>
  
  <pre><code>string attachment = "attachment; filename=Test.csv";
  HttpContext.Current.Response.Clear();
  HttpContext.Current.Response.ClearHeaders();
  HttpContext.Current.Response.ClearContent();
  HttpContext.Current.Response.AddHeader("content-disposition", attachment);
  HttpContext.Current.Response.ContentType = "text/csv";
  HttpContext.Current.Response.AddHeader("Pragma", "public");
  HttpContext.Current.Response.Write("my,csv,file,contents");
  HttpContext.Current.Response.End();
  </code></pre>
  
  <p>My Fiddler capture gave me the following:</p>
  
  <pre><code> HTTP/1.1 200 OK
   Server: ASP.NET Development Server/10.0.0.0
   Date: Wed, 18 Sep 2013 22:06:19 GMT
   X-AspNet-Version: 4.0.30319
   content-disposition: attachment; filename=Test.csv
   Pragma: public
   Cache-Control: private
   Content-Type: text/csv; charset=utf-8
   Content-Length: 20
   Connection: Close
  
   my,csv,file,contents
  </code></pre>
  
  <p>But, the browser is not downloading any CSV file.
  Please help.
  Thanks,</p>
