      Description

      We use correlation Ids in our flows to help with digging into errors, by logging them and returning them to clients.

      After using an http:outbound-endpoint the CorrelationId was preserved in the flow, however with the http:request the CorrelationId seems to be lost from the message.

      Is this desired behaviour? If so, it means that I should be wrapping {{http:request}}s with an enricher to prevent losing the CID. But this really seems unnecessary. I doubt that this is the desired behaviour, so I'm raising the question.

      Here's an example flow that shows how the Cid is persisted across the first http:outbound-endpoint but is lost after the http:request

          <http:request-config name="HTTP_Request_Configuration" protocol="HTTP" doc:name="HTTP Request Configuration"/>
          <http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8098" basePath="test" doc:name="HTTP Listener Configuration"/>
      	<flow name="testpostFlow1" >
      	    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8099" path="testpost" doc:name="HTTP"/>
              <logger level="INFO" doc:name="Logger" message="setting correlation Id"/>	    
              <scripting:component doc:name="Groovy">
                  <scripting:script engine="Groovy"><![CDATA[message.correlationId=message.id]]></scripting:script>
              </scripting:component>
              <logger level="INFO" doc:name="Logger" message="Before http:outbound: #[message:correlationId] / #[message.outboundProperties['MULE_CORRELATION_ID']]"/>
      	    <http:outbound-endpoint exchange-pattern="request-response" method="POST" address="http://localhost:8098/test" mimeType="application/x-www-form-urlencoded" doc:name="HTTP"/>
              <logger level="INFO" doc:name="Logger" message="After http:outbound: #[message:correlationId] / #[message.outboundProperties['MULE_CORRELATION_ID']]"/> 
              <http:request  path="/test" method="POST" doc:name="HTTP" port="8098" host="localhost" config-ref="HTTP_Request_Configuration">
              </http:request>
              <logger level="INFO" doc:name="Logger" message="After http:request: #[message:correlationId] / #[message.outboundProperties['MULE_CORRELATION_ID']]"/>
      	</flow>
          <flow name="testcidlossFlow">
              <http:listener config-ref="HTTP_Listener_Configuration" path="/" doc:name="HTTP"/>
              <logger level="INFO" doc:name="Logger" message="    Inside other service/flow: #[message:correlationId] / #[message.outboundProperties['MULE_CORRELATION_ID']]"/>
              <set-payload doc:name="Set Payload" value="Some response"/>
          </flow>
      

      Output:
