PingIntelligence provides an XFF policy for your decoy APIs. The XFF policy adds an 'X-Forwarded-For' to the backend only if it is not present in the original incoming request. If the 'X-Forwarded-For' header is already present in the incoming request, the policy takes no action.
Follow the steps 1-4 of Axway Policy Studio configuration to import the XFF policy. Deploy the XFF policy after importing.
