[config] "sess_cookie_name" ignored when using redis driver

Hi all,

when I use redis as the session driver, the "sess_cookie_name" value is ignored. The key in Redis server is always starting with "ci_session:...", regardless of the sess_cookie_name value. Can someone tell me how to fix or bypass this? I really need different values for my different environments (dev, qa, production).

Thanks in advanced,
Matthias
