IIRC, it's not needed for mp2, since it's been implemented directly in
mod_proxy
the basic add/deny based on ips is. there is no x-forwarded-for
munging in it -- i searched the 2.059 source. it only adds headers
on a reverse proxy. i'll post the code below from proxy_http.c
i did find
mod_rpaf
http://stderr.net/apache/rpaf/
mod_extract_forwarded
http://www.openinfo.co.uk/apache/index.html
since they're in c, they might be faster- but you need to complile
them as they're non-standard. this works with a simple include. and
it has all my neat features for proxy misc stuff.

It lacks IPv6 support.
Yeah, that was a feature i just didn't want to add in-- I'm not good
w/ipv6, and knew i'd mess it up

* These request headers are only really useful when the mod_proxy

* about the client can be passed through the reverse proxy and on
* to the backend server, which may require the information to
* function properly.
*
* In a forward proxy situation, these options are a potential
* privacy violation, as information about clients behind the proxy
* are revealed to arbitrary servers out there on the internet.
*
* The HTTP/1.1 Via: header is designed for passing client
* information through proxies to a server, and should be used in
* a forward proxy configuation instead of X-Forwarded-*. See the
* ProxyVia option for details.
