I am using mod_cluster 1.2 as a load balancer and JBoss AS7 as nodes. I have configured AJP connector in JBoss and mod_cluster is connected with JBoss nodes.

I want to achieve the following,
Client <–HTTPS–> Balancer <–AJP–> JBoss

Here is my mod_cluster configuration,

LoadModule actions_module modules/mod_actions.so
LoadModule alias_module modules/mod_alias.so

When JBoss is not registered with mod_cluster, and I try http://localhost it is redirected to https://localhost. But when a JBoss node is registered the HTTPS redirection is not working. It is opening the page in HTTP mode only. Please help me to resolve this.

EDIT:

As per karm’s suggestion I have configured the Worker<–HTTPS–>Balancer configuration. But still same effect. When Jboss is registered with m_c, the redirection is not working.

Here is my m_c configuration,

After JBoss is registered with m_c the link http://localhost:8800/mcm itself not working.

Here is the debug logs from m_c,

The problem is with mod_cluster 1.2.0. I took latest mod_cluster code and compiled and used. The HTTPS redirection worked like charm.
