If a user clicks the logout button, I set a field in my table to LoggedIn = False. But what if they just close the browser? Then the database still thinks they're logged in. Is there a way for sessions to accomplish this task?
You can use session on your site or cookie. You can config session/cookie that them destroy than browser close.
