Rewriting HTTPS to HTTP on IIS7

Hi, 

We have a requirement to redirect an existing HTTPS URL (non-IIS hosted) to a IIS7 HTTP site. The IIS7 site doesn't currently have SSL enabled. If the source https://host/12345 URL is to be rewritten tohttp://host/12345, would the IIS7 server need to first enable SSL with certs, etc before we can rewrite the URL? 

Thanks!
