Exercise 1 : Additional Lab Exercise
Note : This lab is not mandatory, it is there if you would like
to take things further. There is little or no sample code although it is
suggested that you use the code from the initial lab exercise as a starting
point.
Using a session
Take the original basic servlet which printed a message to the user and
amend it to display the number of times the user has visited the page.
For this you will need to use the HttpSession class and a good starting
point is the Javadoc for that class. It is a good idea to create a new
servlet called SessionServlet for this lab exercise.
When the user first visits the page the servlet will create a new session
and associate it with this user. Each subsequent time the user visits the
page the servlet will display a page count. Try viewing the same servlet
from different browsers, notice the different page counts.
Extensions
Ask the user for the password before creating the session.
