[users@httpd] Can a server be a member of more than one balancer group?
I have a situation where I may have to do some context-dependent
balancer routing.
I presently have a global balancer which can load-balance to any of the
target servers:
<Proxy balancer://global>
# IP addresses have been changed to protect the innocent
BalancerMember ajp://10.0.1.10:8009
BalancerMember ajp://10.0.1.20:8009
BalancerMember ajp://10.0.1.30:8009
BalancerMember ajp://10.0.1.40:8009
# etc
</Proxy>
And
ProxyPass /cLabs balancer:/global/cLabs
However application-specific and URL-specific circumstances can arise in
which I need the user to be in one of a smaller group of servers:
<Proxy balancer://specific>
BalancerMember ajp://10.0.1.20:8009
BalancerMember ajp://10.0.1.30:8009
# etc
</Proxy>
and
ProxyPass /cLabs/EDSI/catalog/Cisco/ICND1
balancer://specific/cLabs/EDSI/catalog/Cisco/ICND1
(written above the previous ProxyPass directive of course).
It seems to work on a quick test. I'm aware of the possible
session-tracking issues that could arise. My questions here are two:
1. Will it cause a problem that a given server (e.g.
ajp://10.0.1.20:8009 above) is in more than one balancer group?
2. Is there a better way of achieving what I'm trying to do?

Why should it five any problems? As long as you point correctly to the
specific balancer group in your proxypass directives everything should be
ok.
