So How Does It Work? -- cont..
This figure shows the overall architecture of a generic system built using SOAP.
This system uses HTTP protocol to pass the SOAP message between the client and the server. The client application calls a client-side proxy object using its native RPC protocol (such as COM for Microsoft platform and CORBA for UNIX). The proxy object uses an XML parser to convert the call into a SOAP packet. This SOAP packet is then transmitted over the net to the web server using the HTTP protocol. The Web server handles the URL connection point of the remote service, and launches a SOAP translator which may be an ASP page, an ISAPI extension, a CGI program, a Perl script, etc. This translator uses a local XML parser to parse out the object name, method name and parameter values from the SOAP package. It uses these values to call the particular method of the server object by the local ORPC protocol, and packages the results into a response SOAP packet. This response is unpackaged by the proxy and presented to the client
