The In and Out Mediators act as predefined filters. Messages, which are in the in path of the ESB will traverse through the child mediators of the In Mediator. Messages, which are in the out path of ESB will traverse through the child mediators of the Out Mediator.
Syntax
In
<in>
mediator+
</in>
Out
<out>
mediator+
</out>
UI Configuration
None.
Usage Scenario
<syn:sequence name="main" xmlns:syn="http://ws.apache.org/ns/synapse">
<syn:in>
<syn:log level="full"/>
<syn:filter source="get-property('To')" regex="http://localhost:9000.*">
<syn:send/>
</syn:filter>
</syn:in>
<syn:out>
<syn:send/>
</syn:out>
</syn:sequence>
Messages coming to the ESB will be sent using wsa:to address and responses will be sent back to the requester.
Note
These Mediators are pointless to be used in Proxy Service sequences. Proxy Services has predefined sequences for in messages and out messages.
