Post XML to PHP via XMLHTTP VB Object

Hi, I'm trying to the MSXML DOM 3 from Visual Basic and send XML to a PHP page that sits on my Apache web server on SCO Unix. This is my VB Code: Dim xmlstr As New XMLHTTP30 Dim sXML As String sXML = "Content-Type: text/xml;" sXML = sXML & "<?xml version=""1.0""?>" sXML = sXML & "<command><commandtext>Initialize</commandtext>" sXML = sXML & "<returnsdata>True</returnsdata>" sXML = sXML & "</command>" xmlstr.open "POST", "http://mywebserver/somepage.php", False xmlstr.send sXML Set xmlstr = Nothing Pretty basic stuff. This succeeds, and at the Apache server level, in the logs I can see the POST request go through. In the file "somepage.php" - all I'm doing is running phpinfo() to see what the server thinks it's receiving. <? phpinfo(); ?> Back at the VB level, I can see xmlstr.responseText which is the output from phpinfo(); I am not getting any HTTP_POST_VARS like I expected to receive. Has anyone done anything like this before? Is this mainly an issue with Apache rather than PHP? Thanks, Sam
