title: Return PDF to WebPage from ASHX
body: <p>I have a web page with a "download" link on it.</p>
  
  <p>Using jQuery I do an Ajax Get to a ASHX file.</p>
  
  <p>In the ASHX I get the Stream of the file.  I then convert the stream to a byte array and return the byte array back to the calling html page;</p>
  
  <p>jQuery</p>
  
  <pre><code>$(".DownloadConvertedPDF").click(function () {
    var bookId = $(this).attr("bookId");
  
    $.get('/UserControls/download.ashx?format=pdf&amp;bookId=' + bookId, {}, function (data) { });
  
  });
  </code></pre>
  
  <p>C#</p>
  
  <pre><code>context.Response.ContentType = "Application/pdf";
  Stream fileStream = publishBookManager.GetFile(documentId);
  byte[] buffer = new byte[16 * 1024];
  using (MemoryStream ms = new MemoryStream())
  {
    int read;
    while ((read = fileStream.Read(buffer, 0, buffer.Length)) &gt; 0)
    {
      ms.Write(buffer, 0, read);
    }
  }
  
  context.Response.OutputStream.Write(buffer, 0, buffer.Length);
  </code></pre>
  
  <p>I don't get an error but also the PDF doesn't display on screen.</p>
  
  <p>Ideally I'd like the pdf returned and the jQuery to launch the pdf in a seperate tab within the browser.</p>
  
  <p>How can I make this happen or what am I doing wrong?</p>
