Conclusion

As you should be able to see it is a relatively straightforward process to switch the recording of session data from ordinary disk files to a database table. This overcomes the drawbacks inherent with ordinary disk files:

The session data is more secure as a potential hacker must be able to log into the database before he can access anything.
The use of multiple servers would not create a problem as all session data now resides in a single central place and is accessible by all servers.
It is much easier to query the database should the site administrator require information about current sessions or current users.
