When APIM forward request to backend it adds 'X-Forwarded-For' header. Is there any way to remove this header? I tired adding inbound policy (set-header - delete) but it does not actually remove this header. This header with IP address is causing me trouble for authentication at backend api.
If I cannot remove the header what is the alternate way to get my request authenticate as due to this header i am getting 401 Unauthorized error.
Backend system is SAP S/4 HANA
