Answer 1

This works fine for me

session1.php :

<?php
    session_start();
    $_SESSION['sVar'] = 'somecrap';
    header("Location: session2.php");
    exit;

session2.php :

<?php
    session_start();
    echo $_SESSION['sVar'];
    unset($_SESSION['sVar']);

Obviously if I refresh session2.php I get an undefined index warning

Are you starting the session in both pages?
