I haven't followed this whole thread, so I may be way off base here:
If you're implementing a filter, you're filter handlers _will_ be called
as many times as neccessary.
You can account for multiple invocations or pass along information in
$f->ctx() see the filter examples on the docs site.
$f is an Apache2::Filter subclass....

I think in general your handlers should be prepared to be called on
subrequests. If one extra request is a problem, just imagine the hilarity
that will ensue when you get a directory request with indexes enabled.
Sounds like more than a laugh a minute.
You can, for example, check $r->is_initial_req and do your thing if so.
Any advice on tracking this down?
