Upload Problem 204, NULL

[hmb2000]

Hello,
I just tried to implement a file-upload (in knowledge of the documentation in upload-file.txt) and I am able to send the POST Data. I made a little C++ client-side programm which sents the soap-login-package and receives the ZM_AUTH_TOKEN and it builds the POST Data.
For background information I took these additional information:
public:howto:htmlforms [Ararat Synapse]
and
How To Build A multipart/form-data POST request
The POST-data looks like this:

POST /service/upload HTTP/1.1
Host: zimbra
Content-Type: multipart/form-data; boundary=12BA21A1BHS_Boundary
Conection: keep-alive
Keep-Alive: 300
Cookie: ZM_AUTH_TOKEN=0_dd97ed9acc10244476ec496db57312c883 ab2537_69643d33363a34366163363835342d383865622d346 331642d613731632d3839303333393630653830393b6578703 d31333a313232353435363836353630303b747970653d363a7 a696d6272613b

The answer from the server is: 204,'null'
So what is wrong???
(The Zimbra_Test Programm is in the attachment, Codegear C++ Builder and Indy-Library 10.1.5), and a little it from Jedi-Library)

I have the same issue while uploading a file with javascript's xmlHttpRequest.
