Before is easy: just insert a resource in the hierarchy that does its
processing and then passes the request along to the real resource.
After is pretty hard with the current architecture. I'd suggest
treating it like it's impossible, although it may be doable with
sufficient amounts of hackery. I'm doing some work to make this sort of
thing easier in web2, but I'm not going to make any promises as to when
that will be done. The particular use-case I'm working on at the moment
is a output filter to add HTTP range support to any resource.
