Mongodb connect-mongo会话在同一个数据库上存储多个应用程序

I have two SailsJS apps that use connect-mongo to store sessions. They are connected to the same MongoDB database and the problem it's when I am connected to the first app, if I go on the second app I'm directly disconnected on the first app and vice versa. I don't know how can I solve the problem.I have two SailsJS apps that use connect-mongo
