An application layer protocol is provided on top of HTTP 1.0/1.1 to allow for COM Automation objects to be invoked over the Internet through IIS/ISAPI servers. The format essentially encodes the automation object's name, method to invoke, and any [in], [out], [in, out] parameters that the method signature requires, packages them up into a custom MIME type and marshals it to the ISAPI dynamic link library (DLL) on the IIS/HTTP server. There, the ISAPI DLL contains the logic to unpack the SOAP request, parses it, creates the Automation object, invokes the method with the marshaled parameters, and then returns any [out] parameters to the caller/client using the SOAP protocol. It is a stateless protocol, meaning that object lifetimes only extend to one method, and are recreated between multiple calls to the object.
A computer-readable medium have stored thereon a data structure for marshaling data between a client computer and a server computer through the Internet, wherein the marshaled data is associated with a method of an Automation object to be instantiated on the server computer, the data structure comprising:
