CirrostratusGlobal variables are accessible across all TCP connections and all events. Local variables are accessible across all events of a single TCP connection.
If don't want the values to be trampled by different connections/clients, you should only use a local variable. A local variable set in one event will be available for that connection across all other events. You can set the default value for a local variable when the TCP connection is established in the CLIENT_ACCEPTED event.
