* $squirrelmail_language is set by a cookie when the user selects
* In case the last session was not terminated properly, make sure
* we get a new one, but make sure we preserve session_expired_*
sqGetGlobalVar('session_expired_post', $sep, SQ_SESSION);
sqGetGlobalVar('session_expired_location', $sel, SQ_SESSION);
* in some rare instances, the session seems to stick
* around even after destroying it (!!), so if it does,
* we'll manually flatten the $_SESSION data
* Allow administrators to define custom session handlers
* for SquirrelMail without needing to change anything in
* php.ini (application-level).
* In config_local.php, admin needs to put:
* $custom_session_handlers = array(
* session_module_name('user');
* session_set_save_handler(
* $custom_session_handlers[0],
* $custom_session_handlers[1],
* $custom_session_handlers[2],
* $custom_session_handlers[3],
* $custom_session_handlers[4],
* $custom_session_handlers[5]
* We need to replicate that code once here because PHP has
* long had a bug that resets the session handler mechanism
* when the session data is also destroyed. Because of this
* bug, even administrators who define custom session handlers
* via a PHP pre-load defined in php.ini (auto_prepend_file)
* will still need to define the $custom_session_handlers array
