I have the folloving function in vb .net:

  Function SendXMLReq() As String
       Dim returnval As String
       Dim xmlhttp As Object = New MSXML2.ServerXMLHTTP
       Dim objXMLSend = New MSXML2.DOMDocument
       Dim allok As Boolean = False
       objXMLSend.async = False
       objXMLSend.loadXML("<?xml
version=""1.0""?><saldo><msisdn>4550100023</msisdn></saldo>")
       xmlhttp.Open("POST", INUrl)
       allok = xmlhttp.Send(objXMLSend)
       If xmlhttp.responseXML.xml <> Nothing Then returnval =
xmlhttp.responseXML.xml
       SendXMLReq = returnval
   End Function

When i look in the trace from serverXMLHTTPTrace i get:

08:01:42.812 ::*0000001* :: <<<<-------- HTTP stream follows below
----------------------------------------------->>>>
08:01:42.812 ::*0000001* :: POST / HTTP/1.1

08:01:42.812 ::*0000001* :: <<<<-------- End
----------------------------------------------->>>>

So the objXMLSend is not send ....

Where do i go wrong ?
