I have installed two GateIn with JBOSS AS  7 servers on two different machines and i start these two by using standalone-ha.xml configuration. Also i installed an apache httpd server in one of theses machine and i configured mod_jk module to the apache httpd server. Then i configured the clustering of the jboss servers with the httpd server according to this documentation. The problem is i got The page isn't redirecting properly error when i request the apache httpd servers configured url when the both jboss servers are running. But if i turn off any one of jboss servers (node) i got the application when i request apache httpd server url.
