setRequestHeader Content Type Error   

Hi 

  I have issue with my ASP page ascessing webservice(.net 2.0) which returns 
an XML document.

ASP Page

            dim strSoapMessage
            Dim url
            Dim XMLDoc
            Dim objError            
            Dim lResolve, lConnect, lSend, lReceive
            Dim status,  , strUrl, aryUrl, i, strTemp, pos
            Dim strUid, strPwd,strContent, rSuccess
            Dim hArr
            httpMd = 
            rSuccess = false
        
            strSoapMessage = "SOAP MESSAGE IN XML FORMAT"

            Set XMLDoc = Server.CreateObject("MSXML2.ServerXMLHTTP"'.4.0")
                        url="http://localhost/GrantPersmission.asmx"
 
            lResolve = 10 * 1000
            lConnect = 10 * 1000
            lSend = 15 * 1000
            lReceive = 900 * 1000
            Err.Clear
            XMLDoc.setTimeouts lResolve, lConnect, lSend, lReceive
            XMLDoc.open "POST", url, False
            XMLDoc.setRequestHeader "Content-Type", "text/xml;soap"'
             XMLDoc.setRequestHeader "SOAPAction", url
            XMLDoc.send strSoapMessage
            'XMLDoc.send strSoapMessage
            Response.Write (XMLdoc.responseText)

    When I set setRequestHeader "Content-Type", "text/xml;soap"' I am 
getting error 

System.InvalidOperationException: Request format is invalid: text/xml;soap.
   at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters()
   at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()

    When I set XMLDoc.setRequestHeader "Content-Type", 
"application/x-www-form-urlencoded"  It works 

I am not in position to set "application/x-www-form-urlencoded" due to 
client cannot change there code.

Please le tme know if you need more information.
