The servlet you write can be used simulataneously by many
users at the same time and each user of the servlet has a
thread. Consider the user and the session one and the same.
Avoid instance variables. An instance variable is any
object owned by a a class. There will be only one of these
per class - not one per user. In general, you can not have
a user modify an instance variable because other users are
also using the same variable.
