> Certain auth schemes, like NTLM, may result in an empty request (no body, content-length:0) being sent to the server first to trigger a 401 auth challenge so as not to waste bandwidth by posting the real message body twice when it knows the first request will result in an auth challenge.
> Libcurl currently has a bug where it will use the specified content-length on this first request instead of sending 0, which will cause subsequent requests to fail because the message body was never sent.
> Since libcurl automatically calculates the content-length based on the POST size, it's not necessary to specify it from Axis2/C. Removing this header allows libcurl to calculate the length and send the correct values during both requests.
> I recommend the content-length setting code be removed because:
> 1. It doesn't appear to be needed
> 2. Curl docs do not recommend specifying a content-length header
> 3. It's currently the only way to get NTLM authentication working (see AXIS2C-1370)
