Sorry to start a new post but my old one is not publish yet and can't have
access.

I posted to quickly,
don't know if it's the good way, but I resolve my problem.

I change in init.php the default path
// base application http path
//$http_path[base] = ( $core_config['ishttps'] ? "https://" : "http://"
).$c_http_host.( dirname($c_php_self)=='/' ? $c_php_self :
dirname($c_php_self));
// TO
$http_path[base] = ( $core_config['ishttps'] ? "https://" : "http://"
).$c_http_host;

and it's ok, so let's start to play now. :-)
Thanks
