I'm attempting to understand how to use session variables with
register_globals off. Listed below are three very simple pages that pass
session variables.
====>>>With register_globals off:
I'm only able to see $ses_var1 if I refer to it with
$HTTP_SESSION_VARS['ses_var1'] or
$_SESSION['ses_var1'] and not by using $ses_var1. This only works if I used
session_register('ses_var1') then set it using
$ses_var1 = "something";. Per everything I've been reading I expected it
to work more like how I have ses_var2 setup but ses_var2 only produces
output on page1.php
Also I didn't expect $HTTP_SESSION_VARS['ses_var1'] to return anything since
I did not declare them as global in page2 or page3.
====>>>With register_globals on:
Same results as above except $ses_var1 does produces output on any page that
asks.
Am I doing something wrong?
Using Windows 2k/IIS, we are also using Linux and Apache but we haven't
upgraded that machine yet.

page1.php

session_start();
session_register('ses_var1');
$ses_var1 = "Hello World";
$_SESSION['ses_var2'] = "huh?";
echo "\$ses_var1 is ".$ses_var1;
echo "<br>";
echo "\$_SESSION['ses var2'] is ".$_SESSION['ses_var2'];
echo "<br>";
?>
