session when open new ie window

Anon

ok, let's say I have aa.php like this:

<?
session_start();
session_register("aa");
$aa="hello";
?>

PHPSESSID is automatically added to the link as a parameter like "bb.php?PHPSESSID=23423dsgfdasd4235423g2435". My question is: is this always automatic by php? Can it be turn on/off?

Yes, it can be turned off in the php.ini configuration file. Also, it is only added to relative URLS (urls without http:// etc on them). This is to prevent sending the session ID to another server. PHP calls automatically adding the session ID "trans-sid" (meaning transparent session id).

Is there anyway to check if that is on or off in php.ini? The reason if I move my php files to anther server and they have it off, then I have to manually add the sid myself. However, if they have it on, I don't want extra stuff.
