(Delphi ActiveX) HTTP SOAP 1.2 Request and Response using POSTDemonstrates a working SOAP 1.2 request and response using POST with a live server. You may try running this example with the URLs and data provided. See http://wsf.cdyne.com/WeatherWS/Weather.asmx?op=GetCityWeatherByZIP for details. Note: This example is correct in theory, but no longer works for live testing because the SOAP service provider (cdyne.com) has made changes or discontinued the free service. Note: This example requires Chilkat v11.0.0 or greater.
