New to CI, I need help with member area - sessions

[eluser]rkitkonsult[/eluser]
Hi,
I’m all new to CI, what I’ve seen so far is really nice!

I have started to try things out. The first problem I have is about sessions. I want a member to be able to login (then starting a session), and for each member page I have to check the session to see that its a loged in user, otherwise redirect. How do I do this in a proper way? Is there anyone having a sample application that handles this?
