Code:

/*
|--------------------------------------------------------------------------
| Encryption Key
|--------------------------------------------------------------------------
|
| If you use the Encryption class or the Sessions class with encryption
| enabled you MUST set an encryption key.  See the user guide for info.

$config['encryption_key'] = "some random string here";

I see that there's ci_session cookies for both www.domain.com and domain.com. I guess I will have to take a closer look at how the cookies are being set.[/quote][/quote]

Yes, but the browser will still make the domain viewable, as that is a cookie parameter, not cookie contents. The browser needs to know which domains the cookie is valid on so that it knows who to send them to - so this part is not encrypted by CI.

It is because the browser will not send a www.domain.com cookie to .domain.com requests that this problem occured, not because CI was not accepting the returned cookie value or browsed domain.
