allowDuplicates for a header/headers is part of the http.properties on the MP. I don’t think there is any workaround other than enabling this and restarting your MP.
For free accounts, pls check with support to see if that possible or not.
BTW, what is the workaround that you found for purchased license and on premises accounts? Gokulakrishnan
Is there any possibility of receiving the entire HTTP header and payload and not kick in the Apigee error handling ? Why is this to be done at a Apigee Instance level?
I have removed “Expires” header before making call to target server, but still I am facing this issue. Is there any workaround that we can do at proxy level only. I mean using any policy. Please suggest.
Also wondered, in trace I am not able to find the “Expires” header !!.
