modcluster (Wildfly) is not detecting Advertize from Apache
Hi,
I am trying to configure WildFly 8.1.0 with mod_cluster. Both WildFly and Apache are running on the same machine. The machine is Ubuntu 12.04 with Apache 2.2.x
Apache is set up correctly (I believe). I have tested that the advertise module is working correctly by running the test class Advertise found in the mod_proxy source code (github). There are no errors in the apache logs.
I am starting the server as follows: ./standalone.sh -c standalone-ha.xml
If any one can see something wrong with the configuration below and help put me out of days of misery, I would be really grateful....
Apache configuration:
-----------------------------
CreateBalancers 1
<IfModule manager_module>
#Listen 127.0.1.1:6666
Listen *:6666
ManagerBalancerName mycluster
<VirtualHost *:6666>
KeepAliveTimeout 300
MaxKeepAliveRequests 0
AdvertiseFrequency 5
ServerAdvertise On
AllowDisplay On
<Location />

<Location /mod_cluster_manager>
SetHandler mod_cluster-manager
Order deny,allow
#Deny from all
#Allow from 127.0.1
Allow from all
</Location>
</VirtualHost>
</IfModule>
VirtualHost configuration:
----------------------------------
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
ProxyPass / balancer://mycluster stickysession=JSESSIONID|jsessionid nofailover=On
ProxyPassReverse / balancer://mycluster

</VirtualHost>
The results of the Advertize test class:
