I need help to find out the issue in configuring the fallback settings. Consider the below target end point settings with the fall back target server.

<HTTPTargetConnection>

<LoadBalancer>

<Server name="pp2url"/>

<Server name="callback1url">

<IsFallback>true</IsFallback>

</Server>

</LoadBalancer>

<Path>/XISOAPAdapter/MessageServlet?senderParty=&senderService=BS_Sender&receiverParty=&receiverService=&interface=SI_OS_Request_StoredProcedure&interfaceNamespace=http://lsco.com/rtc/API_StoredProcedure_POC</Path>

</HTTPTargetConnection>

The target is the soap based webservice and requires authentication.

Issue:

If the pp2url is not found or having issue, the apigee is invoking the callback1url - but giving error. Whereas if I used the callback1url in the place of pp2url, the flow returns success response. Can you please help us resolving this issue?
