  Tutorial: Solving the logout problem properly and elegantly

Summary Properly handling the logout process in a password-protected Web application requires more than just calling the invalidate() method on the HttpSession object because most modern browsers, with the Back and Forward buttons, allow users to go back

Tutorial Details:

This article presents solutions for properly handling the logout problem along with sample programs. Author Kevin Le starts by describing an ideal password-protected Web application. He then uses sample programs to illustrate how the problems manifest themselves and discusses the solutions required to fix the problems. By centering the discussion on JavaServer Pages (JSP), the article presents the concepts that can be easily understood and adopted for other Web-tier technologies. Le concludes his discussion by showing how building Web applications with Jakarta Struts can more elegantly solve the logout problem. Sample programs for both JSP and Struts Web applications are included.
