Hello All,
I have a web application developed in PHP. We are working on fixing XSS issues and some security issues. We have an issue as below:
When a user logs in, we create a cookie and its stored in browser. And when user browsers the pages the cookie is used to know if the user is logged in. From one window the user clicks some link which opens another window with the same cookie. What we want to do is when the user closes the new opened window or the main window, we want to destroy the cookie. We are opening the new windows as
var de=window.opne("a.html");
Can anyone give me a solution.

Thanks & Regards,
Gowni

Immeditely before opening the new window you can nullify or delete the cookie.
To nullify do this:
document.cookie="TheSessionCookieName=;path=/;";
var de=window.opne("a.html");

To delete use this:
document.cookie="TheSessionCookieName=;path=/;expires=Fri, 27 Jul 2001 02:47:11 UTC;";
var de=window.opne("a.html");


But you CANNOT delete the cookie for one window and let it stay for old window. All cookies are global for one domain and same Realm.  A realm is simply a directory and all subdirectories on the web server.

You could try using an onunload or onblur event for the body, but I'm not sure if that would be executed if the window were closed as opposed to loading a different page. You could also put a close wndow button on the new page which not only closes the window, it deletes the cookie.

Regardless, you should set a short expiration period for the cookie.

Hi,
Thanks for your responses. But I think I was not so clear in explaining. Sorry about that.
When a user logs in, he is broswing some pages and opens some new windows while browsing. When he will close any of the window, the cookie should be deleted.

Thanks & Regards,

The cookie can be deleted like this:

document.cookie="TheSessionCookieName=;path=/;expires=Fri, 1 Jan 1980 01:01:01 UTC;";
