Summary: NTLM authentication and POST wrong behavior

Initial Comment:
Hi,

I found a wrong behavior in CURL.
My libcurl version is 7.18.2.
My OS is Windows XP, the server I'm testing is windows 2003, and the server is IIS 6.

The wrong behavior I get:
Wnen I do POST with NTLM Authentication, I get 400 Bad request.

I used WireShark to viw the traffic and I saw the following:
1. POST is performed with "Content-Length: 214" + data.
2. Response 401.
3. POST is performed with "Content-Length: 214" with no data !!
4. Response 401.
5. POST is performed with "Content-Length: 214" + data.
6. Response 400 Bad Request.

I would expect the POST in paragraph 3 to send either "Content-Length: 0", or attach the data.

I'm not familiar with CURL too much, so I briefly did the following change to fix the issue:
I commented the following code, in http.c in line 2661:
  case HTTPREQ_POST:
/* my comment
    if(conn->bits.authneg)
      postsize = 0;
    else
*/

This fix did the trick to solve the issue.

I hope that you'll supply a better fix than that.
I don't have an open site for it, so I can't attach a link.
I work in RadView, and I had a similar issue in the past, I worked then with Daniel Stenberg.

Regards,
Yossi
