The 404 error is defined as a regular expression too and is matched if no one of currently defined regular expressions match current URL.
To retrieve the 404 regular expression call the function with the argument route_not_found
(available only if not in CLI mode).
$mf('/', function () {
echo 'Hello World!';
});
$mf($mf('route_not_found'), function () {
echo 'Error 404: Page not Found';
});
This is part of the microframework Utilities.
