Unseting session from external file

The problem is that i have the file "login.php" where i start a session 

session_start();
$_SESSION['uname'] = $uname;

so according to this i am redirected to a file "main.php" which includes "header.php" where i have a button with a "href" to external file:

<a href="logout.php" action="includes/process.php" method="post" ><li>Logout</li></a>

This external file includes:

<?php
unset($_SESSION['uname']);
?>

But the real question in here is when i press this button and goes to "logout.php" and executes the code, why i can back to the previous main page ? And i forgot to tell that have an error:Undefined variable: _SESSION in C:\xampp\htdocs\rootFolder\logout.php on line 3

or if i use session_destroy: session_destroy(): Trying to destroy uninitialized session in C:\xampp\htdocs\rootFolder\logout.php on line 3

on external file "logout.php" you did not started session "session_start()".

Use this code in External "logout.php":

<?php
   session_start();
   unset($_SESSION['uname']);
?>

You have to use session_destroy() instead of unset(). 

<?php
    session_start();
    session_destroy();
    header("Location: login.php");
?>

And you have to start_session() at the top of all your files.
