I believe the second session id can be avoided since PHP knows it just created the session id for the first time. Test script: --------------- <?php ini_set("session.use_strict_mode", "1"); ini_set("session.save_handler", "files"); session_start(); ?> Expected result: ---------------- " Set-Cookie: PHPSESSID=k6brqpp9rnh2ajo2tch4l68t84; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-type: text/html " Actual result: -------------- " Set-Cookie: PHPSESSID=k1hn6r22om8kiq60nq72hhsa52; path=/ Set-Cookie: PHPSESSID=k6brqpp9rnh2ajo2tch4l68t84; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-type: text/html " ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66469&edit=1
