I am wanting to implement a push callback facility whereby on the server, I have multiple callbacks for which the callback payload is to be destined for. What I require is to be able to on the server, distinguish one InvokerCallbackHandler from another. Is there a way to add extra configuration around the time I call Client.addListener() from the client?
That's a good question. Such a facility doesn't currently exist. If you want to contribute a solution, I would be open to it.
