This can be achieved by SMS (Session Mgmt Server), which comes bundled with TAM for eBusiness. But simple one way to achieve this is:
1. Implement a HTTP Session Listener class, which will get called whenever a new session is created or destroyed.
2. Create a table in the database, which will store the session count.
3. Increment counter every time a new session is created and decrement every time a session is destroyed.
