Although the actual soap method call is intercepted correctly there are actually two request when a SOAP action is performed:

• Receiving the WSDL, for example http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL
• POSTing the http://wsf.cdyne.com/WeatherWS/Weather.asmx with <?xml version="1.0...

The first part is not done yet.
