Nowjs, Issue with Express

[Eysenck Gómez]

Hi all, sorry, but I wanted to ask if any of you have used with express nowjs, I've tried to make an application day in real time, using these technologies, but I have many problems, my project is to make a kind of web poker-style games, where there are canals and rooms, and you create a room and another person joins and can play, once the room is destroyed, and so on. I have had many problems, such as when the same person does not add to a group, for that I rely on the connect.sid, when I create a room on the server I have an array of rooms, each room has an array of usuarios_cookie, ie connect.sid I keep the user's cookie, to prevent a doubling two tabs to be recognized as another user, the problem is when the tab for example doubled my system recognizes the same user but when I close the I check the event tab "disconnect" in nowjs, and look at all my array of rooms from my server, if his was the connect.sid usuarios_cookies user is disconnected, and if so to remove that connect.sid of usuarios_cookie array of my room. The problem is that when doubled and close a tab being in my room, it is recognized as a "disconnect" and accidentally delete the list connect.sid usuarios_cookie of that room. Please if
