How can I manage more than one client in the proxy?

[emartinezpinzon]

The option to store the id and the secret of the client in the backend and only to receive the credentials of the user and then attach the credentials of the client to make the request of the tokens seems interesting to me and I have read that they recommend doing this in several publications. However, I have two doubts about this.

1. How could I manage more than one client in my proxy?

2. How could you identify the requests among different clients?
