[Zope] Using SSL with Zope/Apache with url rewriting.

Hi all, I've got my Zope server happily working away behind apache, using URL rewriting. But given as I don't entirely understand URL rewriting or virtual host monsters yet, I have almost no idea how to get SSL working. I need a secure connection to Zope. SSL on apache is working fine, using a dummy certificate. Thanks for any direction you may be able to give me. Alec Munro
