$request_use_auto_globals
Specifies if Smarty should use php's $HTTP_*_VARS[]
($request_use_auto_globals=false) or $_*[] ($request_use_auto_globals=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.
