[Zope] Make Zope Web site private?

I want to restrict access to my Zope Web site. Our company's new name must be kept secret for some months, even as I create the new Web site in Zope. I need to view the pages as they will appear to anonymous users, but can't risk anyone else seeing them. The Zope server is running on a remote Linux host. The pages that would otherwise be public (e.g. the index_html methods) need to be available only to me for a time. I don't have the expertise to create a special index_html to require a password, but that's something like what I would want. I could play around with the port number, too, but that's tedious and not really a solution. Has anyone solved this problem? Thanks in advance, Jon Whitener Detroit Michigan USA
