[Zope] Do I understand this correctly?

[Tiller, Michael (M.M.)]

I've been trying to understand how to setup virtual hosting and I have a few simple questions...

1) After reading the VHM documentation (that you can access when you create an instance of a VHM) that the VHM mechanism relies on something upstream (e.g. Apache) rewriting the URL to include this structure that VHM talks about?  More to the point, is it correct to say that VHM is worthless without such a priori URL manipulation?

2) It seems like access rules are sufficient for what I want to do (host different sites from a single Zope server, each with their own directories).  However, when I tried to use the simple example from Zope.org at http://zope.org/Members/4am/SiteAccess2/vhosting, I couldn't get even the simple DTML Method code in Example 2 to work.  It just didn't seem to do anything.  Is that example current with the site access and access rule functionality in Zope-2.6.2?
