You can add php.ini variables to the Apache Virtual Host section for
each site, for example:

php_admin_value session.save_path "/path/to/new/session/folder"


This will override the save path for each site you add it to, but all
other values will be picked up from the system default.

You must make sure the Apache user has write access to the new folder.
