note 83865 rejected from function.setcookie by mgf

Note Submitter: philippe dot sang at prestashop dot com ---- Hi, I need to know how long I can set my cookie (expires time), the MAXIMUM I could set for IE6 compatibility. I have heards about bugs everywhere for IE6 : if expires time is too long, IE will never set cookie (it only works with a couple of IE, like 5% of them doesn't work). So, anyone here know what maximum expires time I can set that I am sure 100% of IE6 will work ? Thanks
