[Ed. note: $HTTP_*_VARS are NO superglobals, only $_SERVER, $_POST, $_GET, $_REQUEST, $_SESSION,
$_COOKIE are superglobals. Therefor you DO need global on the $HTTP_*_VARS, but not on the real
superglobals. ]
Note: When using the magic superglobals (i.e. $HTTP_SERVER_VARS) inside a function, you still have
to declare them as "global" inside the function source.
This is counterintuitive -- you'd think that the built-in variables would automatically have
universal scope -- but necessary.
