	This example application demonstrates server-side and client-side logic
	for services based on WS-ReliableMessaging (which uses WS-Addressing).

	WS-ReliableMessaging provides a reliable message sequence mechanism. A
	message sequence is created by the WS-RM source (e.g. client), the
	messages follow with possible acknowledgements and resends of
	unacknowledged messages in between, then the sequence is closed and
	finally terminated. Sequences can expire, to allow local resources to
	be reclaimed.

	WS-ReliableMessaging may not be useful to improve the reliability of
	request-response message exchanges between two parties over HTTP, since
	receiving a response obviously indicates successful delivery of the
	request.

	WS-ReliableMessaging is useful to improve the reliability of one-way
	asynchronous messaging, for unreliable data gram messaging
	(SOAP-over-UDP), or when responses are relayed to other destinations,
	such as response messages that are relayed to destinations indicated by
	the WS-Addressing ReplyTo header. It is also useful when multiple
	sources are sending messages that arrive in different order or must be
	flagged as an incomplete message assemble when messages are missing as
	defined by the notion of a sequence of related messages.

	WS-ReliableMessaging ensures that all messages must have been received
	for the message sequence to terminate normally (indicated by the
	DiscardEntireSequence behavior). Messages in a sequence are enumerated
	and message acknowledgements are message ranges received.
	Acknowledgements are normally sent to the source to help identify which
	messages should be resend. Acknowledgements can also be send to a
	destination, the AcksTo destination server.

	This header file illustrates two gSOAP soapcpp2 tooling tricks to
	enable services to accept SOAP Fault messages (the SOAP_ENV__Fault
	message definition below) and to create a one-way service operation to
	handle WS-Addressing relayed responses (the ns__wsrmdemoResponse
	one-way message definition below) to accept a response as a service
	request.

	Compile with (note the use of soapcpp2 -a to handle http action header):

	soapcpp2 -a -c -Iimport wsrmdemo.h
	cc -Iplugin -o wsrmdemo wsrmdemo.c stdsoap2.c soapC.c soapClient.c soapServer.c plugin/wsaapi.c plugin/wsrmapi.c custom/duration.c

	Alternative compile step, to use SOAP-over-UDP testing (no HTTP!):
	cc -Iplugin -DWITH_UDP -o wsrmdemo_udp wsrmdemo.c stdsoap2.c soapC.c soapClient.c soapServer.c plugin/wsaapi.c plugin/wsrmapi.c custom/duration.c

	Alternative compile step, to use OpenSSL for HTTPS:
	cc -Iplugin -DWITH_OPENSSL -o wsrmdemo_ssl wsrmdemo.c stdsoap2.c soapC.c soapClient.c soapServer.c plugin/wsaapi.c plugin/wsrmapi.c custom/duration.c -lssl -l crypto
	With SSL enabled, please make sure that server.pem, cacert.pem, and
	client.pem are copied with your executable.

	Usage:

	After compilation, start the main server:
	> ./wsrmdemo

	In a new window, run the client:

	> ./wsrmdemo hello
	This example shows the main server returning "hello" to the client.
	WS-RM message acknowledgements are also returned to the client as
	piggy-backed headers, so the client keeps track of ack'ed messages that
	do not need to be resend.

	> ./wsrmdemo hello d
	This example shows the main server returning "hello" to the client in
	duplex mode. The client uses a callback polling service to accept
	response messages on a port.

	> ./wsrmdemo hello ds
	This example shows the main server returning "hello" to the client in
	duplex mode. The client uses a stand-alone (non-polling) callback
	server to accept response messages on a port.

	> ./wsrmdemo fault
	Simulates a fault generated by the server. The fault is non-fatal and
	processing resumes until the sequence is terminated.

	> ./wsrmdemo fault d
	Same, in duplex mode with callback polling.

	> ./wsrmdemo fault ds
	Same, in duplex mode with callback server.

	> ./wsrmdemo error
	Simulates an error generated by the server. The error is fatal and
	further processing is refused by the server.

	> ./wsrmdemo error d
	Same, in duplex mode with callback polling.

	> ./wsrmdemo error ds
	Same, in duplex mode with callback server.

	Note 1: when the ReplyTo service is down, the response cannot be
	relayed and the client (or the fault service when FaultTo is set) will
	be informed about the failure.

	Note 2: HTTP Basic authentication can be enabled by setting the
	following values in wsrmdemo.c:
		const char *userid = "...";
		const char *passwd = "...";
	The client operations set HTTP Basic Auth while server operation check
	it. The WS-RM CreateSequence, CloseSequence, and TerminateSequence do
	NOT check the credentials of the client (only the sequence messages).
	Of course, and incomplete sequence abnormally terminates when the
	behavior is set to DiscardEntireSequence.  To upgrade to HTTP Digest
        authentication, register the HTTP digest authentication plugin at the
        client and server sides.

	Note 3: HTTP compression can be enabled by compiling the sources with
	-DWITH_ZLIB. Then use SOAP_ENC_ZLIB flag to send compressed messages.

	Note 4: HTTPS can be enabled by compiling with -DWITH_OPENSSL.

	Note 5: The client is set-up for two-way messaging, so UDP one-way
	messaging is not demonstrated. This also leads to timeouts at the
	client side when no response is received (and no acks or faults). To
	implement one-way messaging, please refer to the documentation.
