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"

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):

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

Virtual Host 1:

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?
