      Setup Apache + mod_proxy and an AJP connector in WildFly, wire it all together. Deploy a simple application that uses SSL session tracking mode (such as: https://github.com/tknyziak/ajp-ssl-session-cce) and try to access it through Apache.

      Setup Apache + mod_proxy and an AJP connector in WildFly, wire it all together. Deploy a simple application that uses SSL session tracking mode (such as: https://github.com/tknyziak/ajp-ssl-session-cce ) and try to access it through Apache.

      In the mentioned setup (HTTPD --> mod_proxy --> AJP --> Undertow in Wildfly), when the web application running on the WildFly server uses SSL session tracking mode, any attempt to access it crashes with a ClassCastException, like this:

      Changing the tracking mode to COOKIE fixes the problem.
