| - | To work with Joomla (cached for guest visitor or logged-in user), LSWS cache relies on a cookie token to differentiate whether a user is logged in or not. However, Joomla assigns cookie to any user (guest and logged-in). cookie value changes as same session go through different stage (such as before login, after login, logout and log back in, etc) while cookie key stays the same. The easy way is the create desired cookie in joomla by modifying its code (small modification in login/logout stage). Login/Logout functions are located in the standard user component (docroot/component/com_user/controller.php). | + | ==== Joomla Code Change ==== |
