if the server is connected to a websocket client using socket.io, what are the events that would cause the client.id to change?
the server reset
the client opening a new connection
are there others, such as timeout?
When client connects to the socket.io server, then new id is generated for the connection. And there is no other place where id is generated.
Server reset, client opening new connection, timeout (and reconnection) - all of this triggers creation of new id, because actually client has to create a new connection to the socket.io server.
