Should general support for a query URL be provided in

Can you explain more? I don't get the question.
What I mean is
• Should mod_proxy_balancer be extended to provide a balancer
algorithm in which one specifies a backend URL that will provide a
single numeric health metric, throttle the number of such requests
via a time-to-live associated with this information, and balance on
this basis or
• Should mod_cluster handle this issue?
• Or both?
Please recall that, afaik, mod_cluster is not AL nor is it part
of Apache. So asking for direction for what is basically an external
project on the Apache httpd dev list is kinda weird :)
In any case, I think the hope of the ASF is that this capability is
part of httpd, and you can see, with mod_heartbeat and the like,
efforts in the direction.
But the world is big enough for different implementations...
You're right -- I was being weird. Sorry.
I guess part of the reason for my asking was whether the ASF was
basically saying "we're not chasing this problem, see mod_cluster folk
if you need it solved" -- and, if so, hoping to get a little starting
info as to what I'd be getting into chasing mod_cluster.
I'd like to see this capability in httpd itself -- or at least have it
very easy to add in a very seamless fashion via a pluggable custom
balancer algorithm (without other larger configuration side effects) --
and thus would hope the ASF sees this as within the scope of httpd's
core suite of modules.
