mod_proxy_balancer can't be used with mod_cluster. So that won't work for the moment.
Thank you for your reply.
In fact I'd like to use a httpd Apache web server (on server 1) to load-balance:
a) 2 JBoss AS with mod_cluster (server 2 and 3)
b) 2 httpd Apache web servers (server 2 and 3)
c) 2 ArcGIS Server (middlewares deployed with Tomcat, see here) (server 2 and 3)
How could I achieve this ? Do I have to get rid of "mod_cluster" and use only "proxy_balancer" ?
c) 2 ArcGIS Server (middlewares deployed with Tomcat,
it would be possible to use mod_cluster (2 jars + some configuration).
b) 2 httpd Apache web servers
that is not possible: you would need a module that sends mcmp messsage to the front-end. Such a module doesn't exist yep but would be easy to create (JIRA?).
Thank you for your reply,
so I'm stuck to "mod_proxy_balancer" for now.
