There are situations where we want to protect your servlet
member variables from being modified by different
clients.In this case you can have your servlet by
implementing the marker interface SigleThreadModel.

Everytime a client makes request to a servlet by
implementing this interface,servlet engine will create a
new instance of servlet.

For performance reason,servlet engine can also maintain a
instance pool,handing out instances as they are needed.Or
it could also serialize client request executing one after
another.
