URL0 always(?) includes the ending published object (eg. index_html).
Normally if you don't want this you just use URL1.

Using URL1 you should get [path]/source.html which would seem to me to be
what you want.

By actual page address you want the URL with index.html instead of
index_html? Given your current setup as described, redirecting would work.

<dtml-call "RESPONSE.redirect(URL1+'/index.html')>

Though this would cause every hit on a page's index to tranverse twice. If
the site isn't super high traffic it wouldn't be noticable.

If you were working with zope projects there are other tricks you could
pull, but it doesn't sound like you are doing this.

In zope there is the URL which represents the object traversal and there is
the returned content (html, images, etc). The returned content (maybe what
you mean by actual page) can feasibly come from some other part of the
site, a database, or just about anything else. The URL or address is just
what method/object gets run to get said content.

Not sure if I'm making this much clearer. But there it is anyways.
