Apache 2.4 issue on proxypass balancing on two BalancerMember [Weblogic 12c]

Question

I have an Apache 2.4.12 on a dedicated machine (RedHat 6.x) that must balance on another machine with two Weblogic Managed Servers (port: 9101 and 9102. Weblogic 12c on RedHat 6.x) where I have deployed the application "Pega".

I have implemented the configuration below on the Apache VirtualHost (myvirtualhost.conf) but if I have both BalancerMember active it doesn't work. If I comment one of the two BalancerMember it works fine.

Do you have any suggestion to fix it?

thanks in advance for your collaboration

<VirtualHost myvirtualhost:443>
    SSLEngine on
    SSLProxyEngine on
    SSLProxyVerify none
    SSLProxyCheckPeerCN off
    SSLProxyCheckPeerName off
    SSLProtocol all -SSLv2

   #Server certificate
   SSLCertificateFile /opt/rh/httpd24/root/etc/httpd/ssl/xxx.cer

   #chiave privata del server:

       BalancerMember https://myweblogicserver:9102

    ProxyPass "/" "balancer://mybalancing/"

</VirtualHost>

Edit: Yes i set correctly parameters. I reach the login page (both when it works and when it doesn't) but when it doesn't work, if i enter my credential, i see:

Status  fail
Message There has been an issue; please consult your system administrator

But if i comment one of the BalancerMember:

<Proxy balancer://mybalancing>
   # BalancerMember https://myweblogicserver:9101
     BalancerMember https://myweblogicserver:9102
</Proxy>

It works fine.

So i guess i miss something in the declaration of 'balancer' , or maybe i miss some directive..

Any suggestion would be really appreciated.

Thanks

EDIT2: Yes the session replication works well between the two servers. I'm able to login using a direct URL to a server (actually a Node in a server, the machine is the same, what changes is the port : 9101 and 9102) and then switch the other server (other node) maintaining my current session.. I guess it's some directive of proxypass but its the first time i face it

To use the WebLogic Web Server plugins, these are the basic steps:

1. Download the .so file and copy to /etc/httpd/modules.

2. Create a file called /etc/httpd/conf.d/weblogic.conf with the following content:

LoadModule weblogic_module modules/mod_wl_24.so

<IfModule weblogic_module>
    WebLogicCluster myweblogicserver:9101,myweblogicserver:9102
    DebugConfigInfo ON
    MatchExpression * 
</IfModule>
