Specifies if Smarty should use PHP's $HTTP_*_VARS[]
when FALSE or $_*[] when
TRUE which is the default value. This affects templates that make use of
{$smarty.request.*}, {$smarty.get.*} etc.
Caution:
If you set $request_use_auto_globals to true,
$request_vars_order has no effect but
PHP's configuration value gpc_order is used.
