[keycloak-user] TCPPING problem.

Dears, I would like to ask a question. I have Wildfly, version   WildFly Full 14.0.1.Final(http://14.0.1.final) (WildFly Core 6.0.2.Final(http://6.0.2.final))    . And then I have Keycloak, version Keycloak 4.7.0.Final(http://4.7.0.final) (WildFly Core 6.0.2.Final(http://6.0.2.final))  . Static cluster configuration, using TCPPING, works in Wildflys, but does not work in Keycloaks. I always have 2 instances on localhost (browser thus sends them the same JSESSIONID).   On both I have deployed a testing clustering webapp, with which to test, if sessions are replicated. But Keycloaks do not pass sessions to each other. I can see that when the page from the second instance is reloaded in browser, it sends Set-Cookie header with another cookie, as it obviously does not know the JSESSIONID from the first instance. With Wildflys the same does work. Can you tell me, is there any reason, why this is the case, when Keycloak uses Wildfly ? Thank you. With regards V. Havlik.
