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.
