No, it's not the correct way (I'm assuming this is a SOAP call). The actual usage of XMLHTTP is usually:

DECLARE Sleep IN WIN32API ;
         INTEGER nMillisecs

lcURL = "http://www.127.0.0.1/SomePage.asmx/MethodName" && Fill in with your info
loXML = CREATEOBJECT("MSXML2.XMLHTTP")
loXML.open("POST", lcURL)
lcSOAP = "SOAP message here"
loXML.send(lcSOAP)

DO WHILE loXML.readyState < 4
   Sleep(100)
   * Add code for timeout here...
ENDDO

IF loXML.readyState = 4
   * Parse response
   lcResponse = loXML.responseText
ENDIF

Building the soap message is actually a major pain. It seems every platform implements this slightly differently and it usually takes alot of messing around with the format to get it right.

I don't have any cookbook style code to help here (I've done this a few different times and hated it every time I needed to get this to work).
