Open Source Windows service for reporting server load back to HAProxy (load balancer feedback agent).

Posted by Malcolm Turnbull 15th August in HAProxy

In general when you are load balancing a cluster you can evenly spread the connections through the cluster and you get pretty consistent and even load balancing. However with some applications such as RDS (Microsoft Terminal Servers), you can get very high load from just a  few users doing heavy work. The solution to this is to use some kind of server load feedback agent.

RDP, however, is not an easy protocol to load balance; sessions are long-lived and need to be persistent to a particular server, and users may connect from different source addresses during one session. The current development version of HAProxy has made an important step forward in making this possible. Thanks to work by Exceliance, it now supports RDP Cookies, offering a solution to the persistence problem.
