Hi,

I am developing a WinNT service on XP SP2(using unmanaged C++) that
communicates with an exchange frontend server using WebDAV.
I am trying to handle forms based authentication based on Henning
Krause's work

http://www.infinitec.de/articles/exchange/webdavwithfba.aspx

I changed the code to use ServerXMLHttpRequest instead of
XMLHttpRequest and I get a 403.
Enclosed code below.

I am at loss to understand why using XMLHttp works and ServerXMLHTTP
fails.
Has anyone come across this before ?

CComPtr<MSXML::IXMLHTTPRequest> pHTTPReq;

hr = pHTTPReq->setRequestHeader(_bstr_t(_T("User-Agent")),
_bstr_t(_T("Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2;

hr = pHTTPReq->setRequestHeader(_bstr_t(_T("encoding")),
_bstr_t(_T("UTF-8")));

hr = pHTTPReq->setRequestHeader(_bstr_t(_T("Content-type")),
_bstr_t(_T("application/x-www-form-urlencoded")));

hr = pHTTPReq->send(_bstr_t(streamBody.str().c_str()));

CString strReplyXML = (TCHAR*)pHTTPReq->responseText;
