All Superinterfaces:

javax.servlet.http.HttpSession
```
public interface Session
extends javax.servlet.http.HttpSession
```
Represents a user's session (login session) in the system. Can hold some additional attributes as needed, but the underlying implementation may limit the number and size of attributes to ensure session replication is not impacted negatively.
