To invalidate a session, my teacher passed the following code:

HttpSession session = request.getSession(false);  
    if (session!=null){
        session.invalidate();
    }

But after logout, when I click Back in the browser, I can retrieve the same one I had logged in to. How do I delete it? Thank you in advance!

Try to use this:

Cookie[] cookies = request.getCookies();
if (cookies != null)
{
    for (int i = 0; i < cookies.length; i++)
    {
        cookies[i].setMaxAge(-1); // se -1 nao funcionar tente 0 nao lembro bem essa parte
        resp.addCookie(cookies[i]);
    }
}

If you read the documentation say that:

 "The server can maintain a session in many ways such as using cookies or rewriting URLs."

Using these lines (or create a method) you will be turning off cookies.

PS: This code has not been tested.
