THTTPReqResp executes a method call on an invokable interface by sending a SOAP message to the server.
THTTPReqResp = class(TComponent, IInterface, IWebNode, IHTTPReqResp);
class THTTPReqResp : public TComponent, public IInterface, public IWebNode, public IHTTPReqResp;
THTTPReqResp handles HTTP-based communication with a Web Service provider on behalf of a THTTPRio instance. THTTPRio uses this component to establish a connection to the Web Service provider and perform two tasks:
It can issue a "Get" request to obtain information from a WSDL document.
It can issue a "Post" request to pass a method call to the server for execution and retrieve the results.
The Web Service that is the target of these HTTP messages can be specified directly, using the SoapAction and URL properties, or it can be taken from the SoapAction in a WSDL document, as specified by the WSDLView property. Additional properties provide details that are included in the HTTP request message header.
