[Mediawiki-l] sessionHandling

[Michael Heyder]

Hi,

so I created a new specialpage. Going on I need some sessionhandling in 
there. At the moment id semms not be startet.

$wgAutoloadClasses['WizardBase']='./includes/WizardBase.php';
$wgAutoloadClasses['naw_WizardFunctions']='./extensions/NewArticleWizard/NewArticleWizardFunctions.php';
class NewArticleWizard
     extends SpecialPage implements WizardBase
{
	public function __construct()
{
....
}
}

So is there a global var which controlls the session or must it be 
startet via session_start(); ?

Thanks for some useful hints
