disable visit tracking for specific pages

[Christian Vogler]

Is there a way to disable visit tracking for specific pages? The only
reason that I have it enabled at all is that the admin area of my web
app is protected by the Identity framework. On the user-visible
portions of the site, visitor tracking is neither necessary, nor
desirable. The site is going to be deployed in Germany, which has one
of the strictest privacy laws in the world, and I would rather
forestall a potential source of problems altogether.

My controller structure looks like this:

Root
index
redirect_to
... (some more user actions)
admin (as SecureResource)
... admin area ...

So, ideally, I would like to have visitor tracking enabled only for
everything below "admin."

Is there a straightforward way to accomplish this? Is there perhaps a
way to restrict VisitorFilter to specific URLs?

Best regards
