You need to specify every exclusion per host, e.g.:

excludedContexts="localhost:ROOT,localhost:docs,localhost:manager,localhost:host-manager,localhost:examples,localhost2:ROOT,localhost2:docs,localhost2:manager,localhost2:host-manager,localhost2:examples"

Git Pull Request:
https://github.com/modcluster/mod_cluster/pull/194, https://github.com/modcluster/mod_cluster/pull/195, https://github.com/modcluster/mod_cluster/pull/196

With the following configuration:

<Listener className="org.jboss.modcluster.container.catalina.standalone.ModClusterListener" 
loadMetricClass="org.jboss.modcluster.load.metric.impl.BusyConnectorsLoadMetric" 
loadMetricCapacity="1" 
loadHistory="9" 
loadDecayFactor="2" 
stickySession="true" 
stickySessionForce="false" 
stickySessionRemove="true" 
advertise="true" 
advertiseGroupAddress="224.0.1.105"
advertisePort="23364"
advertiseInterface="10.40.4.50"
excludedContexts="ROOT,docs,manager,host-manager,examples"
/>

And these contexts in webapps:

clusterbench docs  examples  host-manager  manager  ROOT

One expects this output on Mod_cluster manger console:

Virtual Host 1:
Contexts:
/clusterbench, Status: ENABLED Request: 0 Disable Stop
Aliases:
localhost

It works, unless you configure additional VirtualHosts:

<Host name="LOCALHOST"  appBase="webapps" unpackWARs="true" autoDeploy="true">
<Alias>LOCALHOST</Alias>
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
       prefix="localhost_access_log" suffix=".txt"
       pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host>

<Host name="KARM.BRQ.REDHAT.COM" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Alias>KARM.BRQ.REDHAT.COM</Alias>
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
       prefix="localhost_access_log" suffix=".txt"
       pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host>

result:

Node worker1 (ajp://10.40.4.50:8009):

Virtual Host 2:

/host-manager, Status: ENABLED Request: 0 Disable Stop
/examples, Status: ENABLED Request: 0 Disable Stop
/, Status: ENABLED Request: 0 Disable Stop
/clusterbench, Status: ENABLED Request: 0 Disable Stop

Aliases:

Virtual Host 1:
Contexts:

/clusterbench, Status: ENABLED Request: 0 Disable Stop

Aliases:

localhost

I find this bug being of Critical priority, because it could coax users into believing they excluded certain context while in fact they didn't.

WDYT? Is it possible to tweak with the Listener's configuration somehow?
