I did some digging and found that MemoryStream works. I updated my code and
it's no longer going to the filesystem. I'm very impressed with what iText
has been able to handle. Here's the code in case anyone ever is interested.
PdfReader readerMain = new PdfReader(Server.MapPath(formFile));
Document document = new
Document(readerMain.GetPageSizeWithRotation(1));
MemoryStream memoryStream = new MemoryStream();
PdfSmartCopy copy = new PdfSmartCopy(document, memoryStream);
document.Open();
foreach (RequestDetail detail in details)
{
PdfReader readerTemp = new PdfReader(Server.MapPath(formFile));
MemoryStream memoryStreamTemp = new MemoryStream();
PdfStamper stamper = new PdfStamper(readerTemp,
memoryStreamTemp);
AcroFields fields = stamper.AcroFields;
... form updates here ...
// flatten form fields and close document
stamper.FormFlattening = true;
stamper.Close();
PdfReader readerTemp2 = new
PdfReader(memoryStreamTemp.ToArray());
copy.AddPage(copy.GetImportedPage(readerTemp2, 1));
}
document.Close();
byte[] b = memoryStream.ToArray();
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Length", b.Length.ToString());
Response.AppendHeader("Content-Disposition",
"attachment;filename=tickets.pdf");
Response.OutputStream.Write(b, 0, b.Length);
Response.OutputStream.Flush();
Response.OutputStream.Close();
Response.End();
