Just do one thing. In your database, in your usertable, add one bit field called IsLoggedin. when user login check for true or false value. If value is true(i.e. already logged in), then automatically redirect to home page. and if value is false(not logged in), then update that value to true, and redirect.

Solution 1

just add status column in your login table and maintain a status as '1' while login and maintain as '0' while logoff for every user.
