Question

My asp .net mvc3 web application is facing issue which is application assigning same session id to multiple user login (using different credentials) that use same browser. After a user log-in using some credentials, then the next time he attempts to login with a different credential using another window in the same browser, I want the user to be redirected to the home page of first login just like in facebook. How can I achieve this? I thought of storing session Id of each user in DB and then check if the session ID is already in when a login attempt is made. But this seem to hit application performance. Can anyone tell me what is the best approach to handle this situation?

Check the property

System.Web.HttpContext.Current.User.Identity.IsAuthenticated

In your login form. If the user is IsAuthenticated then redirect them to their homepage instead of the displaying/processing the login form.
