<castle>
<facilities>
<facility id="rhino.esb" >
<bus threadCount="1"
numberOfRetries="5"
endpoint="msmq://localhost/nhprof.backend"
/>
<messages>
<add name="NHProfilerWeb.Backend.InternalMessages"
endpoint="msmq://localhost/nhprof.backend"/>
<add name="NHProfilerWeb.Messages"
endpoint="msmq://localhost/nhprof.backend"/>
</messages>
