How to properly redirect user to other page upon login?

Hi,

I'm new with CI. I'm still learning it, and hope to make my project with this framework. I have a simple question.

Before I started learning CI I was writing non OOP simple PHP apps, and used header("Location: ") to redirect the user upon successful or failed login. I've searched trough the docs and found redirect($uri = '', $method = 'auto', $code = NULL) function, does that do the same thing as far as I can see.

Should I still use the header() function or the CI built in redirect(), or should I use something different for this kind of task and similar tasks?

Thanks in advance!
