Tomcat not invalidating sessions xp pro non validating
The Cluster module uses the Tomcat JULI logging framework, so you can configure logging through the regular logging.properties file.To track messages, you can enable logging on the key: .The valve rewrites the JSESSIONID value in the cookie with the same name.Not having this valve in place, will make it harder to ensure stickiness in case of a failure for the mod_jk module.Remember, if you are adding your own valves in then the defaults are no longer valid, make sure that you add in all the appropriate valves as defined by the default. Trick: You can enable this mod_jk turnover mode via JMX before you drop a node to all backup nodes!Hint: With attribute session Id Attribute you can change the request attribute name that included the old session id. Set enable true on all Jvm Route Binder Valve backups, disable worker at mod_jk and then drop node and restart it!The all-to-all replication is an algorithm that is only efficient when the clusters are small.
To get around this problem, you'll want to use the Backup Manager.is the flag that is attached to each message sent by the Simple Tcp Cluster class or any objects that are invoking the Simple Tcp method.The description of the send flags is available at our javadoc site The element.This manager only replicates the session data to one backup node, and only to nodes that have the application deployed.Downside of the Backup Manager: not quite as battle tested as the delta manager.
