<div dir="ltr">As Petr mentioned, We have a few clustered tomcat applications and we use both, a hardware load balancer and tomcat's session replication. The load balancers job is to just direct traffic to the available nodes. We do not cluster midpoint but it should still work the same, we use CAS sso for midpoint which does it's own session management. Setting up session replication in tomcat is not too difficult, the below should get you started,<div><br></div><div><a href="http://tomcat.apache.org/tomcat-8.0-doc/cluster-howto.html">http://tomcat.apache.org/tomcat-8.0-doc/cluster-howto.html</a><br><div><br></div><div><br></div></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">JASON</div></div></div>

<br>
In a clustered setup <a href="https://wiki.evolveum.com/x/xwCp" rel="noreferrer" target="_blank">https://wiki.evolveum.com/x/xw<wbr>Cp</a> are the midPoint instances aware of each other's sessions? So if the user logs into node A, and then load balancer connects the user to node B, is node B aware of the user's session?<br>
