mod-jk

In my configuration i used Apche+mod_cluster as a front_end(load balancer) server and two JBOSS AS 7.1.0 as backend server.

In my configuration on one system i have install Apache+mod_cluster + JBOSS AS 7.1.0 and on other system JBOSS AS 7.1.0. Both JBOSS AS 7.1.0 are in domain mode means in clustering.

My problem is that if Apche+mod_cluster crash than client can not access any JBOSS AS .

I want to configure Apache+mod_cluster in Master_Slave format, means if one of Apache+mod_cluter down another Apache+mod_cluster become active and pass client(browser) request to back-end server in normal form without any interruption.

Is there any way to make two Apache+mod_cluster to communicate with each other , means to check health status of each other and if any one get down other Apche+mod_cluster will do it's task ......
