note 22710 deleted from ref.session by sniper

For automatic session initialization on every page, you have to set the flag session.auto_start = 1 in php.ini. And you will get a warning in row 0, php couldn't open the session file, when your path for session files is set relative like this: session.save_path = ..\tmp, which can work perfectly with the session_start() functions. If changing autostart to 1 und having a relative save_path for sessions, the absolute directory path changes. That's because the path no longer refers to the current scripting file (where sesson_start() was executed before) but the system itself. Using Apache the tmp directory is to add to the folder "Apache Group". Than it works again.
