Triton Digital needs to have visibility of the user-agent and the IP address of the listener at the HTTP level. With player-to-server implementations, this information comes directly from the player (and thus, the listener). But with server-to-server implementations, it refers to the server, not the listener. For this reason, server-to-server implementations must be explicit with this information. **You must configure your implementation so that the listener's user agent string and IP address are appended to the ad request**. For more information, see [Ad Request Parameters](/user/docs/od-ad-request-parameters) and [Custom Streaming Environments](/user/docs/custom-streaming-environments) in the *Triton Digital On-Demand Specification.*
