How do I pass variable to the redirect module?

id = '39252';

if cms.system.redirect('external_id': id, 'query': ['foo': 'bar']);

exit;

end;

In this code example, we’re establishing a variable ('id') on the first page, and then during the cms.system.redirect function, we’re passing the value of that variable to a URL parameter which will be maintained through the redirect process. This can be helpful to maintain query parameters for redirects and other similar situations.
