Well, I'm not sure, but..
Did apache notisted that JBoss went down?
If not, you have a config problem in Apache and not JBoss..
Apache gives me following message if i take down one of the severs.
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /jboss/servlet/submit.
Reason: Could not connect to remote machine: Unknown error
But it does not redirect me to the other server listed in the httpd.conf file under mod_jk directive. Any clues what i might be doing wrong? I ahve put in the enteries in the httpd.conf on Apache for both of the servers.
I guess you should be putting the directives under mod_proxy not mod_jk.
I was able to do it in a different way.... i used the following configuration int the http.conf
JkMount /*.jsp loadbalancer
JkMount /servlet/* loadbalancer
JkMount /examples/* loadbalancer
and doing the configuration of the loadbalancing in the workes.properties....
