 +DokuWiki opens the session in ''inc/init.php''. After some things are initialized it is closed again. This is because PHP locks the session and this session lock may halt background requests like images, ajax, etc.
 +Depending on when your plugin runs, the session might already have been closed. You can still read a closed session's variables but writing will have no effect. If you need to write to it, you need to call ''session_start()'' again, use the session as usual and close the session with ''session_write_close()'' again.
 +:?: When in code does it close? How to detect? If one tries to (re)open a session which is currently not closed, he get's an error.
 +:!: To re-open a session, no chars must be sent to the clients browser.
