i have a few questions about GPaaS.
1. how to save zone & room when deploy a new application? (every time i upload a new application, sometimes the room & zone are deleted so i have to create one).
2. how to intercept a request from user when user is trying to connect to the server? (i want to decide whether this user can / cannot connect to the server)
3. i read documentation about remove user
* remove a user from the zone. the user will get disconnected from the server.
* @param user the user to be removed
public void removeUser(IUser user);
how to use it?
