Files sent via HTTP port seems to disappear.

I have tried to send some files via biztalk 2004 and a http send port, but
although the HAT claims they are sent correctly they seem to have disappear.
I have then set up a testpage on my own mashine to receive the files, and
found out, that if you expect to recive them like a "file post" with .Net
code like this:
foreach(string f in Request.Files.AllKeys)

{

HttpPostedFile file = req.Files[f];

tmpFilename = file.FileName;

tmpFilename = " c:\\inetpub\\wwwroot\\sslmodtag\\Uploade
dFiles" +
tmpFilename.Substring(file.FileName.LastIndexOf("\\"));

file.SaveAs(tmpFilename);

}

}

The files will "disappear". However if you use this code:

BinaryReader r = new BinaryReader(req.InputStream);

string tmpFilename =
" c:\\inetpub\\wwwroot\\sslmodtag\\Uploade
dFiles\\test.txt";

FileStream filStream = new FileStream(tmpFilename,FileMode.CreateNew);

byte[] bytearray = r.ReadBytes(500000000);

filStream.Write(bytearray,0,bytearray.Length);

All seems to work just fine.

My question is, since the supplier I need to send theese files to, use the
first method to receive files, how do I make Biztalk sent it in a way it can
be received? Is it really nessesary to write my own HTTP adapter?

Hope for an "easy" solution to my problem :-)

Yes, that expected because the Request.Files Property expects a MIME-encoded
HTTP request body. Also the Content-Type HTTP header needs to be set to
"multipart/form-data". (See .NET doc on the Files property for the details).

BizTalk Server can produce MIME encoded requests, but this approach makes
only sense it you need to transfer more than one file per request or if you
want to retain the file name during transfer.

To make BizTalk Server produce MIME encoded requests, you'll need to create
your own send pipeline and put the MIME encoder pipeline component in the
Encode stage.
