PDF Size will increase in size dramatically with every submit.

I have a PDF Form desinged using Adobe LiveCycle Desinger ES2.

It has a submit button which will submit the form to the server (IIS and ASP.NET) using this javascript command:

event.target.submitForm( {cURL: "http://server/ASPNETWebPage.ASPX", aPackets:["datasets","pdf"], cSubmitAs: "XDP"});

On the server, from ASP.NET, I use the following code to extract the submitted "chunk" element and convert it from Base64 to Binary PDF File:

            fs = New System.IO.FileStream(mFormFileNameFolder, IO.FileMode.Create)
            bw = New System.IO.BinaryWriter(fs)
            ' Get chunk element form the submitted XML
            Dim srChunk As New StringReader(mXML.GetElementsByTagName("chunk")(0).InnerXml)
            Do While True
                Dim theChunkLine As String
                theChunkLine = srChunk.ReadLine
                If Not String.IsNullOrEmpty(theChunkLine) Then
                    theReadBytes = theChunkLine.Length
                Else
                    theReadBytes = 0
                    Exit Do
                End If
                Dim theBase64Length = (theReadBytes * 3 / 4)
                Dim buffer() As Byte
                buffer = Convert.FromBase64String(theChunkLine)
                bw.Write(buffer)
            Loop
            bw.Close()
            bw = Nothing
            fs.Close()
            fs = Nothing

The above code is working fine, and PDF is generted successfully.

I have one problem.

With every submit, the generated PDF Size will increase dramatically. I reported this to Adobe Support, and they cofirmed that this is by desing and that with every submit, the previous PDF State is saved, and the new state is added. That is why I get huge PDF File.

I was told that the only way to solve this problem is to submit the form as PDF ONLY, and after I save the PDF File on a file system, I then must use Adobe Service/Process "exportData" to extract the XML Data from the PDF.

I think this is really big change to me. I was hoping that there is a way to indentify the latest PDF State from the chunk element.

Any help will be greatly appreciated.
