using iTextSharp to create PDF that opens in browser

I'm using Itextsharp to call a page and then create a pdf from the contents of that page. I want the file to either open in the browser or allow the user to save. The included code creates a file, but gives the following error when trying to open it.

Adobe Reader could not open '' because it is either not a supported file type or because the file has been damaged.

If I use PdfWriter.GetInstance(document, new FileStream("c:\\Application" + bb + ".pdf", FileMode.Create)); the file is created on my file system perfectly, but since the site will sit on a server, I don't want it to work that way. What can I do to fix this?

try
        {
            string bb = Request.QueryString["pid"];
            Response.ContentType = "application/pdf";
            Response.AppendHeader(
              "Content-Disposition",
              "attachment; filename=test.pdf"
            );
            using (Document document = new Document())
            {
                PdfWriter.GetInstance(document, Response.OutputStream);
                WebClient wc = new WebClient();
                string htmlText = wc.DownloadString("http://myserver/GeneratePDF/CreatePDF.aspx?pid=" + bb);
                Response.Write(htmlText.Replace("\r", "").Replace("\n", "").Replace("  ", ""));
                List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(htmlText), null);
                for (int k = 0; k < htmlarraylist.Count; k++)
                {
                    document.Add((IElement)htmlarraylist[k]);
                }

            }
        }
        catch (Exception ex)
        {
            Response.Write(ex);
        }

I've never used iTextSharp, but the documentation at this site says you need to call Close() on your document.

If that doesn't solve the problem another option you might consider is rather than writing directly to Response.OutputStream you could try capturing the output into a MemoryStream and then using Response.BinaryWrite to send the file from the MemoryStream.
