note 58707 added to function.session-start

Why session can't pass to another page?(use php 4.4.0) I wrote two php pages: 1.php <? session_start(); $_SESSION["login"] = true; $_SESSION["admin"] = "name"; echo "<a href=\"2.php\" target=\"_blank\">2.php</a>"; ?> 2.php <? session_start(); var_dump($_SESSION); ?> i access 2.php through 1.php , but it outputs: array(0){} Why ? i have tried many times . but sometimes it works as i want but more times it doesn't work! ---- Manual Page -- http://www.php.net/manual/en/function.session-start.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58707 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58707&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58707&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58707&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58707&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58707&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58707&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58707&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58707&report=yes Search -- http://master.php.net/manage/user-notes.php
