Send SOAP 1.2 Request to Web Service Requiring Authentication

See more HTTP Examples

This example demonstrates sending a SOAP 1.2 request to a web service that requires both HTTP authentication in the Authorization request header, as well as a service-defined password in the XML body of the request. Delphi ActiveX
