问题 I have a servlet which calls a jsp page. In the servlet I am retrieving the username provided at the login correctly. But after setting the same in session, when i access the called jsp page, its returning null. Servlet Code: public class AdminServlet extends HttpServlet { /** * */ private static final long serialVersionUID = -4244742541587179390L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String userName = request

问题 Hi I have a php file that is empty and the only line of code in there is <?php session_start(); ?> No html mark-up or any php code besides the code above. On localhost it doesn't trigger an error, but when it's on the server and I visit the page, a new line is printed on the error log that says [25-Apr-2016 05:43:34 UTC] PHP Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at path/to/file.php:1) in /path/to/file.php on line 1 The server is

问题 I'm running a Django app for my root public_html folder, and it's working fine. But there's a problem with one of my other apps. The problematic app is accessed through a redirect to a subdirectory (e.g. http://workingsite.com redirects to public_html, http://brokensite.com redirects to public_html/foo) The problem is that the session expires whenever anything needs to be saved in the Django admin (either added or changed). If you try again, sometimes it works. This does not happen on my own

问题 I've always wondered why PHP makes you manually session_start() in order to gain access to the immensely useful $_SESSION "super-array". It strikes me that this might be causing a lot of stress on the server, but not really make a difference in practice unless you have an extreme amount of users. I don't really see why it would cause such a strain, though, if you don't use that array/mechanism. And if you do, you always want session_start() to have been called... It would really be nice to

问题 I am working on a project of PHP. I have a strange error. My PHP project is working well on local server (WAMP server). But after hosting it on live server, it is not working. Problem: Session variable created on Login.php page is not passing value on Report.php page.

问题 just hope this is not a stupid question. I have an eCommerce site and when user adds an item to cart. On top of the page I have this function which count the array and then shows the user how many item is in cart. Then I am store the total cart price in a session to show show on top of the page as well. I am using Jquery to add an item to cart but the problem is you have to refresh the page to so that you can see the total cart item and total cart price(On top of the page. Not the cart page.

问题 Recently I stumbled on an interesting bug where entries would show up in our local custom-made ticket system from users that didn't exist in the app. After some poking around I realised that both this and another PHP app running on the same server were using $_SESSION['user'] for authentication purposes. When someone used one system and then opened the other one he was "automatically" logged in as a user from the first app. After the obligatory facepalm I changed the session variable name in
