controller_website_redirect
This controller does a redirect to the website property of the given resource.
The required id argument can be a resource id or name. The resource must
exist and be visible to the current user. When its website property is not
empty, the controller returns a temporary redirect to that URL; otherwise no
redirect is produced.
This controller is selected by controller_page when a resource has
is_website_redirect enabled. Relative website values are expanded against the
current site URL.
