Hi Folks,
Just to briefly explain how other messaging scenarios are made to work with
the relay:
1. A special handler checks whether security or some other content aware
module is engaged on the target service and builds the messages if
necessary.
2. Each mediator knows whether they should build the message or not
(depending on their configuration). If necessary, mediators will build the
message.
As a result a sequence such as the following will run in the pure pass
through mode:
<sequence>
<log/>
<send/>
</sequence>
Something like the following will cause the message to be built at the log
mediator:
<sequence>
<log level="full"/>
<send/>
</sequence>
In the following proxy service, the in-sequence will be in the pass through
mode. The out-sequence will build the message at the xslt mediator:
<proxy name="foo">
<target endpoint="bar">
<inSequence>
<log/>
</inSequence>
<outSequence>
<log/>
<xslt key="baz"/>
<send/>
</outSequence>
</target>
</proxy>
Thanks,
Hiranya
