State Management and the HttpSession

This free, multimedia tutorial shows you how to use IBM's Rational Application Developer (IRAD) 6.0 to create a simple Servlet that takes advantage of the HttpSession object of the Servlet and JSP API. The simple Servlet uses a hitcounter to keep track of the number of times the petulant user refreshes the web page.
