To be honest I currently have no generic idea how to do this without support from the backend. My point was more about that I would love to see this health check integrated into the generic code of mod_proxy and its connection pooling and let the protocol modules provide the code that actually does the dirty work of the protocol specific aspects of such a health check. This would make it easy to add health checks for other protocols / add better ones for protocols with existing ones. As said currently I would only see two health check providers: - CPING/CPONG for AJP. - A generic TCP connection check. But this would be open to further bright ideas. Regards Rüdiger
