ASMX webserive not recieving parameters from classic ASP soap request.

Question

I am attempting to wrap a newer .net ASMX webservice so that it can be used by an older classic asp application. To do this I found some code to send the soap requests. However in my testing it seems that none of my parameters are reaching the server.

The Server Test Code

   <WebMethod()> _
    Public Function Ping1(str As String)
        If str <> "" Then
            Return str
        Else
            Return "False"
        End If
    End Function

The xml being sent:

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <Ping1 xmlns="http://tempuri.org">
      <str>asdf</str>
    </Ping1>
  </soap12:Body>
</soap12:Envelope>

The page keeps returning "False" but as far as I can tell, this should be the right format to send parameters. Any help would be appreciated.

As demonstrated in this other question you should set proper headers when consuming the service:

oXmlHTTP.setRequestHeader "Content-Type", "application/soap+xml; charset=utf-8" 
oXmlHTTP.setRequestHeader "SOAPAction", "http://ourNameSpace/Ping1"

Note that you can't use tempuri.org namespace, you have to also set your own namespace.
