.htaccess and php save session path

Hi!

I have AllowOverride setting on my /var/www/html/ directory.
I have /var/www/html/site1 folder wich contains an .htaccess file with the
following statements

DirectoryIndex index
<Files "index">
ForceType application/x-httpd-php
AcceptPathInfo On
</Files>
php_flag short_open_tag on
php_flag implicit_flush off
php_flag display_errors off
php_flag log_errors on
php_value error_log phpErrors.txt
php_flag register_globals off
php_flag magic_quotes_gpc on
php_value default_mimetype text/html
php_value default_charset iso-8859-1
php_value include_path .:../php/includes
php_value session.save_path ../php/sessions
php_value session.use_cookies 1
php_value session.name userid
php_value session.auto_start 0
php_value session.cookie_lifetime 0
php_value session.gc_maxlifetime 28800
php_value session.cache_limiter none
php_value session.cache_expire 480



For some reason a site in /var/www/html/site2 starts to save its php
sessions in folder ../php/sessions despite the fact that php.ini says it
should be /tmp

Any help appreciated!

Thanx!
