[Zope] Re: Access Rules

[Chris McDonough]

How do you define a "page"?  I consider a "page" the thing rendered
when a user visits a URL.  Since access rules trigger on any URL
visitation, this means you can write a log of "pages" visited via an
access rule.  But it seems you are defining "page" in a different
way; what defines a "page" to you?

Do you want to track all calls to other Zope objects inside a Zope
object?  This is very difficult and probably not worth it.  The logs
generated would be huge and would have pointless amounts of detail,
most of which you probably wouldn't care about.
