Bleck. mod_dav just shoves brigades into the output filters. It should "just
work". No need for proxying or any such stuff.

The problem stems with getting the (PHP) filter inserted into the output
filter chain, rather than any specific issue with mod_dav.

[ the concept here being that mod_dav simply supplies content to the chain;
  get the filters arranged properly, and you'll be set ]

Note: I'm not trying to shift blame off of mod_dav. I'm not going to state
it is Perfection Incarnate(tm). It is simply that mod_dav behaves in terms
of the "ideal" "content generator" and that Apache "ideally" should be
setting up a (output) filter chain to process the generated content
appropriately. The *goal* of the Apache filter design is to enable this
situation, so if we aren't getting the PHP filter in there, then the Apache
design needs to be tweaked.
