  • Hi,

    You can do that with a SoapExtension. A SoapExtension is a mechanism provided by ASP.NET to intercept all the SOAP messages that goes to an specific web service.

    This sample in the MSDN shows how to implement a SoapExtension to trace all the SOAP request/response messages.

  • Hi,

    You have to add some custom code to read the server variables in your web service class, or just add that code in a soap extension.

    You can get the server variables from the HttpContext,
