如何运行另一个控制器中存在的Logout方法 - Codeigniter

I have a view include/Header.php in which I have this part

#This is to display the `Menu list` if the user has logged in else dont show this `Menu list`

if($this->Membership->checkLogin()){
echo "<li><a href='http://localhost/nams/Login/Logout'>Logout</a></li>";      
}

After successful login I redirect the controller Login to Application.

In the Application controller when it runs index I am loading the include/Header view, and the menu is shown.

The anchor link is http://localhost/nams/Login/Logout.

From the controller Application, when I click on the link, it shows 404 error.

What is the reason for this error ?
