Hello, I've written a simple application, where users need to login to access the features of the application. I want to develop login system such that, if user is already logged in, the application should not allow the users to login with the same login credentials. How do I accomplish this? Regards, Balu

Just save the credentials, for a valid user, in a session and check to see if a new login submission matches. Be certain to lowercase everything so as to prevent a simple case change from appearing to be a different user.
