note 21163 added to language.variables.predefined

I discover that variables registered through $HTTP_SESION_VARS (i don't use session_register() ) (in PHP 4.0.6) are not saved if i make a server redirect to another page, so i can not use them in this page. Why? If a use $_SESSION array (i understood that it's auto-global) in php 4.1.0 it's ok, the variables are registered. I had only changed $HTTP_SESSION_VARS with $_SESSION and of course php version. I need help to understand why?
