I have a web page that manages logeo and full CRUD of the users satisfactorily, all managed with java session. As a new requirement I have been told that users can only have a single session started.
I have been looking at possible solutions, one may be to increase a field in my user table that detects whether the session is started or not, and then make an algorithm that prevents logging in until this value changes.
Now if the session class of java has its own methods to solve this problem and someone is also welcome your answer
