Rerouting a function or changing its url

[eluser]Zac G.[/eluser]
Hi,

I have a function that logouts out a user. I would like it to send the user back to the homepage after they logout. How would I do this? Or can I change the url from site/logOut to just site after the logOut function runs?

I think this should be a pretty simple process, but I am a new to working with CI and not sure how to do this.

Thanks!
