"If you don't see the redirect menu in the user panel, this option will only be shown when your webserver is configured for Apache Only."
^ Seems redirects would be a necessary thing no matter what web server was being used.
The CWP team does charge for one-time requests, so I definitely see them charging for something like this. Also, even after setting that redirector file one has to reload the config or manually edit the .htaccess file under the public_html folder.
