О шаблоне
The 04.Session Tracking mind map template provides a structured overview of session management in Java web applications, covering 53 nodes across techniques, cookies, HttpSession, and event handling. It explains the stateless nature of HTTP and introduces key session tracking methods such as URL Rewriting and Hidden Form Fields. The template details cookie operations using javax.servlet.http.Cookie, including methods like getMaxAge() and setValue(), and demonstrates sending cookies via response.addCookie(). It also explores the HttpSession interface with methods like getAttribute() and invalidate(), and covers session event listeners such as HttpSessionAttributeListener and HttpSessionBindingListener. This session tracking cheat sheet is ideal for Java developers preparing for interviews or building web applications.

The template covers 53 nodes organized into five main branches: Session Tracking basics, Techniques (URL Rewriting, Hidden Form Fields), Cookies (javax.servlet.http.Cookie methods), HttpSession (methods and timeout), and Event Handling (listeners and events).
Open the .xmind file in Xmind, then explore each branch to understand session tracking concepts. You can customize the nodes by adding your own code examples or notes, and use it as a study guide or reference during development.
Yes, the template is fully editable in Xmind. You can add, remove, or modify nodes, and export it as an image or PDF for printing.
URL Rewriting appends session ID to the URL, while Hidden Form Fields use a hidden input element to pass the session ID via request.getParameter(). Both are used when cookies are disabled.
Call the invalidate() method on the HttpSession object to destroy the session and remove all associated attributes. This is useful for logout functionality.
The template covers HttpSessionAttributeListener (attributeAdded, attributeRemoved, attributeReplaced), HttpSessionBindingListener (valueBound, valueUnbound), and HttpSessionListener (sessionCreated, sessionDestroyed).
