actually, apparantly, that's not strictly true with tomcat (and other
2.2+ servlet engines?) - if the bytes that have been written to the
outputstream have not been flushed yet, then it is still possible to send
redirects and set http response headers. there's a method you can use to
check - response.isCommitted().

oh, and what about content aggregation? i'd think that'd be on the todo
