You need to call
session_start();
On any page that you wish to access the $_SESSION global array from.
Working from your example below.
1.
call session_start() before you set the session variable on page 1.
(I have heard some people say that it is not necessary to do this as the
$_SESSION is a global array, however, I have had difficulties when I went
with this option so I think it is better to call start_session();
You do not need to call session start on page2, however, unless you do you
are not able to access the $_SESSION array
On page 3, call session_start() and then you will be able to access the
$_SERVER array.
This snippet of code allows you to inspect your session variables.
<?php
foreach ($_SESSION as $key=>$val){
echo "SESSION:: $key :: $val<br>";
}
?>

PHP holds session in the $_SESSION global array, it's not magically held
in the page. Once it's in there, unless you destroy the session, it's in
there. There are TONS of tutorials on session management online.
