    if ($_SESSION['login'] == false) {
  echo ' <script> location.replace("../logout.php"); </script>';
}


define("SESSION_FILE", "session_data.txt");

function fetchDataWithSession($url)
{

    // Check if the session data file exists and read its contents
    if (file_exists(SESSION_FILE)) {
        $sessionData = unserialize(file_get_contents(SESSION_FILE));
        $_SESSION = is_array($sessionData) ? $sessionData : [];
    }

    // Initialize cURL session
    $ch = curl_init($url);

    // Set cURL options
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    
    // Pass the session data in the request headers
    $headers = [
        'Cookie: ' . http_build_query($_SESSION, '', '; ')
    ];
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    // Execute cURL session and get the response
    $response = curl_exec($ch);

    // Check for cURL errors
    if (curl_errno($ch)) {
        // Handle error
        echo 'Curl error: ' . curl_error($ch);
    }

    // Close cURL session
    curl_close($ch);

    // Write the updated session data to the file
    file_put_contents(SESSION_FILE, serialize($_SESSION));

    // End the session
    session_write_close();

    return $response;
}

$protocol = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? 'https' : 'http';
$host = $_SERVER['HTTP_HOST'];
$path1 = rtrim(dirname($_SERVER['REQUEST_URI']), '/');
$path = "$protocol://$host$path1/action.php";

// $sessionData = fetchDataWithSession($url . '?getSessionData=true');
