I am developing an application with trame.  
If I open several browser windows I see the same image and, if I rotate or execute any view operation (ex. zoom) I see the same image in both browser windows.  
I tried to use @server.controller.add(“on\_client\_connected”) and @server.controller.add(“on\_server\_ready”) but I do not know how I can identify an unique identifier for each client.

If you are trying to setup a multi-client environment, you should use our docker bundling infrastructure to automatically start one trame process per client connecting to the service.
