We've recently configured a new Cluster with the following configuration:
www.mydomain.com | APACHE + MOD_JK (AJP) Load Balancer / \ Tomcat1 Tomcat2
All the requests are made through HTTPS and the two tomcat instances are using SessionReplication via DeltaManager.
The cluster and all the wep-apps are working just fine.
Now one of these webapps requires the use of WebSockets with WSS:// protocol and i'm getting this exception
java.lang.UnsupportedOperationException: HTTP upgrade is not supported by this protocol
Has anyone ever a clue on what is causing this ?
