#2018/7/6 update. Since io object which PFA use to keep a connection to database can't be stored in session since it contains SSL context
# we have to maintain it in memory for every user. We will store a unique key in user's session and with that key, the user can access to
# his in memory io object. The problem needed to pay attension is that key must be randomly generated or only known to the current user
# otherwise, if other user get the key, they can easily change their local session and obtain other users io object to access other's db
# We have to clear the in memory io objects table regularly or keep only a limited number of items to limit the memory
# solution: each time the user login, a random number will be generated accosiated with his io object
# at the same time, a new timing thread will start to count down 2h. After 2h, the io object will be destory
# currently, we allow a maximum of 100 users login. If the number exceed, we assume it is under attack and will reject login request
# a public default login session for demostration will never be shut down
