How to stop different users logging in at the same time
I have set up Thingworx with forms login, some of my users have multiple logins, as they look after other users. If they happen to already be logged into a user account and then in the same browser login again, it causes issues with the sessions data which I store in the user extensions properties.
I need as way to stop multiple logins occur on the same browser, I would be happy of there was a way to know if a user was logged in already or not, so I could then redirect the user to the home page.
I have been trying to make changes to the FormLogin.jsp page, but have had no luck so far. Is there anything I can do to see if a user already logged in from the FormLogin.jsp page? Or any other suggestions on handling this situation?
