/*
        asyncsoap3.c

        Example synchronous versus asynchronous pipelined SOAP messaging

        Compilation:
        $ soapcpp2 -c -CL -r -wx async.h
        $ cc -o asyncsoap3 asyncsoap2.c stdsoap2.c soapC.c soapClient.c

        Run by starting the webserver with HTTP pipeline and keep-alive
        enabled at port 8080, then run asyncsoap3:
        $ ../webserver/webserver -ek 8080 &
        $ ./asyncsoap3
