[wildfly-dev] How to configure Wildfly to use the InMemorySessionManager instead of DistributableSessionManager?

Further to a previous post for session problems in my application, I believe some of my issues relate to the DistributableSessions that are being used by Wildfly. However, in my configuration file, I have my web cache defined as a local cache: <subsystem xmlns="urn:jboss:domain:infinispan:4.0"> <cache-container name="server" aliases="singleton cluster" default-cache="default" module="org.wildfly.clustering.server"> <transport lock-timeout="60000"/> <replicated-cache name="default" mode="SYNC"> <transaction mode="BATCH"/> </replicated-cache> </cache-container> <cache-container name="web" default-cache="passivation" module="org.wildfly.clustering.web.infinispan"> <local-cache name="passivation"> <locking isolation="REPEATABLE_READ"/> <transaction mode="BATCH"/> <file-store passivation="true" purge="false"/> </local-cache> <local-cache name="persistent"> <locking isolation="REPEATABLE_READ"/> <transaction mode="BATCH"/> <file-store passivation="false" purge="false"/> </local-cache> </cache-container> ... ... I see that undertow comes with an InMemorySessionManager, but not entirely sure how to enable it. Do I have to go through the effort of creating my own ServletExtension and configuring it in the META-INF/services/io.undertow.servlet.ServletExtension or is there an out-of-the-box way of enable functionality that already exists via the config file? Thanks, Eric
