How does the use of header('Location: http://www.domain.de/gb_status.html') in PHP affect browser history when redirecting from a POST request to a GET request?

When using header('Location: http://www.domain.de/gb_status.html') in PHP to redirect from a POST request to a GET request, the browser will not retain the POST data in its history. To preserve the POST data, you can redirect using a GET parameter instead. This way, the data will be included in the URL and can be accessed after the redirect. 

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Process the POST data
    
    // Redirect with GET parameter
    header('Location: http://www.domain.de/gb_status.html?data=' . urlencode(json_encode($_POST)));
    exit;
}
?>
