Hi FRIENDS: can anybody give me a concept about implement ONE SIGNIN at the same time?
if I use servlet or jsp to implement it the way I consider about is below: 1 record the sessionId and userId in some media(db), then we'll know who is login and who is not 2 use a demon program to determine whole sessionId which is live and correspond to db's data if some session is dead then demon program will remove from db how to get whole sessionId which is live? does it work or anybody has more intellegent idea about it? thanks
