I've put up a quick blog entry here: http://blog.loadbalancer.org/open-source-windows-service-for-reporting-server-load-back-to-haproxy-load-balancer-feedback-agent/
With links to a source code tar ball for haproxy including Simons patches. I've also just open sourced (GPL'd) our Windows based service and GUI for sending load information back to HAProxy. Links included in the post. Its not fully debuged or tested yet, but its getting very close if anyone wants to give it a go. Any feedback appreciated , thanks. Ps. We've also got ldirectord patches to work with it if anyone wants those... -- Regards, Malcolm Turnbull. Loadbalancer.org Ltd. Phone: +44 (0)870 443 8779 http://www.loadbalancer.org/
