If an unexpected error occurred with a request, the HTTP_MCP controller will be called again with the ProcErr argument populated. The nature of the error (usually a runtime error) will be contained in the ProcErr argument. This routine is a template for generating a response so the caller will receive a well formatted reply.
The procedural error data being passed in from the OEngineServer. Unless otherwise changed, the only reason this should be called is if there was a runtime error in one of the stored procedures that was called by the initial request.
HTTP_Aborted_Service handles aborted HTTP Requests either due to Runtime Errors or Status Errors. If the Debugger Intercept has been enabled, this handler will only receive Status Error aborts.
