Lighttpd

need something like this for lighttpd:

http://cvs.pld-linux.org/cgi-bin/cvsweb.cgi/SOURCES/mod_rpaf_degtine.patch

mod_rpaf always uses the last value from the X-Forwarded-For header as
the client IP, breaking when you have several chained proxies (i.e.
Pound in front of Squid in front of Apache).

The attached patch makes it use the last address in the header which is
not in RPAFproxy_ips, falling back to the first one if they are all
known proxies.
