Hello there and welcome to the Wowza support forum.
I am not sure what you are trying to do here, but you can take a look at this guide:
How to re-stream an unprotected stream from Adobe Media Server or a CDN
NOTE: HTTP ingress is only supported for ShoutCast streams, the guide I linked to is limited to re-streaming the RTMP stream. Wowza Streaming Engine does not support ingesting A/V streams using the HTTP or HTTPS protocol.
If this does not answer your question, could you please provide more detail about your particular use case?
