User Authentication - Placement of code?

[eluser]RyanH[/eluser]
That makes sense. I'm attempting to test this but for whatever reason, I can't get a few things to work before I can test this. The first being I can't get the logout link to work. I've read the user guide for URL's and I thought it made sense, but it's apparently not working. I created a logout function in the login controller file that does the following:

Code:

$this->session->sess_destroy();
$this->load->view('home_view');

The session is destroyed and the user is shown the home page once the session is destroyed. The link that I have is this:

Code:

// 'login' is the class (it's also the file name) and logout is the function as per the user guide
anchor('login/logout', 'Logout');

However this is not working. Perhaps I just don't understand how CI handles URL's.

Secondly, it seems as if each page I go to while I'm "logged in", a new session is created. Any particular reason? Anyway to fix this? Thank you for your help!
