some comments on sessions
- $PHPSESSID will only be set after the first page refresh.
- SID will only be set if your not using cookies.
- sessions with not transfer across multiple domain names.
- sessions without cookies will not transfer accross full urls.
<?php
if (isset($PHPSESSID))
session_start($PHPSESSID);
else
session_start();
$PHPSESSID = session_id();
$SID = "PHPSESSID=$PHPSESSID";
?>
use this code and
- sessions will transfer across full urls when using $SID
- sessions will transer across multiple domain names on the same server
using $SID
- both $PHPSESSID and $SID are set allways set.
remember that header redirects *require* full urls so you will have to use
$SID.
header("Location: http://$SERVER_NAME/index.php?$SID");
