Please suggest free java-based load balancer for fail-over clustering. It should understand that http server down and route requests to another server. When server up again - it should include them into rotation.

Yes, I know that each server generally has own load-balancing. We develops cross-paltform application that supports Tomcat, Jetty, JRun, Weblogic, WebSphere, Resin, etc and its difficult to describe cluster configuration for each server.

I know load-balancer from jetty, but it can't understand that server is down.

Director 5.1 is probably in release now. Its open-source.

Thank you, I checked Director 5.1 and some other systems and understand that we need additionally following:
- Windows native (not Cygwin) support or Java
- Standalone (not just plugin to IIS/Apache/etc).
