htaccess + auto_prepend_file failuere

[MJuhler]

Hi, I have searched the forum and could not find other topics about this problem so I hope someone can help me.

In the /www I have a htaccess file containing the following:
php_value auto_prepend_file ../design/header.php
php_value auto_append_file ../design/footer.php

and it works fine, my problem is that when I call a page "list.php" located in /www/callback folder via "$("#show").load("callback/list.php");" so problems arise.
*
in callback folder is a htacces file with the following content:
php_value auto_prepend_file none
php_value auto_append_file none

and even to the rims htaccess file in the callback folder should not throw design of the file list.php then throw the design of anyway via htaccess file from the /www

It has worked in the past when we used Apache as web server, I hope there is someone who can help me
