Invalidating the session

Session Management in Java Servlet Web Applications is a very interesting topic. Http Session; /** * Servlet implementation class Login Servlet */ @Web Servlet("/Login Servlet") public class Login Servlet extends Http Servlet When a JSP resource is used, container automatically creates a session for it, so we can’t check if session is null to make sure if user has come through login page, so we are using session attribute to validate request. Servlet Exception; import javax.servlet.annotation. Session in Java Servlet are managed through different ways, such as Cookies, Http Session API, URL rewriting etc. Checkout is another page and it’s code is given below. Pressing the back button in your browser is simply pulling the page from your local cache, not making a new request. When I press back, in next request, I can access to the attributes of session.If you call the invalidate() method, then the session is gone.Please feel free to post any easier way to destroy a particular session.Because it's quite useful for functionality of force an user offline.1.I try to implement a web page for disconnection to delete the user data (password, credit card), but if the user presses back after the disconnection page it recovers the data.

Using generic php session methods to delete a particular session(by session id).Invalidating a session is server-side logic, the back-button is purely client-side logic.You might set the appropriate HTTP headers when you send pages to the browser to tell it it should never show cached pages but instead always send a new request.I'm using PHP 7.1 and received the following warning when implementing Example #1, above: PHP message: PHP Warning: session_destroy(): Trying to destroy uninitialized session in...What I discovered is that clearing $_SESSION and removing the cookie destroys the session, hence the warning.
