[keycloak-user] Searching for a class named org.keycloak.services.filters.ClientConnectionFilter

in order to run a keycloak-server on tomcat, I am searching for a class named org.keycloak.services.filters.ClientConnectionFilter. Could anybody send me a hint where to find it? Could anybody share a link to a documentation of this filter? -- Gruß burghard.britzke https://britzke.berlin/
