note 15549 deleted from function.setcookie by sniper

1. if you set 'expire' to 0 the cookie expires 'this session'. (can be handy) strange behaviour 2. if you specify a path, the cookie vars are only available in those directories! And strange enough the path string is cumulative: cookie in "/test" is also available in "/test2" and "/testbed". But cookies set in "/testbed" are not available in "/test" etc. i.e. a partial path string DOES match !! (not good) Furthermore, i see in explorer(mac) that for all subdirs a 'accept cookies for www.domain.com' is set. This IS a problem if you work on several projects in subdirs that use the same cookie var names, for instance used in a common AUTH-LIB. And if you use different var names, you can only work on 20 projects (max cookies per domain) tr909
