Little problem with php4/5

[thid]

I was trying to setup diffrent php version for each catalog in one domain. I have edited /etc/apache2/mods-*/fastcgi_ispcp.conf

Code:

AddHandler php-fastcgi .php5
<Location /php5/php5-fcgi-starter>
   SetHandler fastcgi-script
   Options +ExecCGI
</Location>
Action php-fastcgi /php5/php5-fastcgi-starter
AddType application/x-httpd-php5 .php5

I added this to fastcgi_ispcp.conf.
So basicly when I use in .htaccess

Code:

AddType application/x-httpd-php5 .php

The server should use php5 for parasing php in the catalog. The problem is that server use php5 for all script in domain

Anyone have ideas what is wrong with this?
