Sesssions specific to folder?

[eluser]sheldonnbbaker[/eluser]
Is there a way to have a Codeigniter session live only relative to a specific folder?

Reason being, on my local server (http://localhost), some userdata session variables are overwriting each other (since they are on the same server).

So can sessions in http://localhost/admin/ folder be separate from sessions in http://localhost/work/some-new-website-project/ folder?

Code:

$config['sess_cookie_name']        = 'whateveryouwant';
