The possible values are:</p><ul><li>before-headers</li><li>after-request</li><li>on-shutdown.</li></ul><p>The default is "after-request", which is the current Resin behavior.Sites which have distribted sessions, but do not have a sticky-sessionload balancer may need to use "before-headers". "before-headers" doesadd a latency penalty.</p></s2></s1><s1 title="java.util.logging fixes"><p>The operation of the java.util.logging has changed to properlyimplement/configure the java.util.logging API.</p><p>For clarification, the <log> tag's "level" attribute setsthe level of the logging Handler. It does not set the level ofthe Logger.</p><s2 title="<logging>"><p>The new <logging> tag configures the Logger, e.g.</p><example><logger name="com.caucho" level="fine"/></example><p>Is equivalent to:</p><example>Logger.getLogger("com.caucho").setLevel(Level.FINE);</example><p>If no <logger> is supplied, the level default to the parent.If no parent has a <logger>, the level defaults to INFO.</p></s2></s1><s1 title="Admin enhancements"><p>Some MBeans have been reworked and extended:</p><ul><li>ClusterClientMBean (resin:type=ClusterClient,name=app-a)</li></ul></s1><s1 title="Load Balancing enhancements"><s2 title="client-connect-timeout"><p>Sets the time a client should wait for a connection to a backend server.Defaults to 5s.</p></s2><s2 title="client-weight"><p>The backend <srun> servers can now have a client-weight, sothe load balancer can distribute more or less load to more orless powerful servers.</p><p>The default value is 100.</p><example><cluster id="app-tier"> <srun id="app-a" client-weight="200" host="192.168.0.10"/> <srun id="app-b" host="192.168.0.10"/> <srun id="app-test" client-weight="1" host="192.168.0.200"/></cluster></example></s2><s2 title="client-warmup-time"><p>The backend <srun> servers can now have a warmup-time.The client-warmup-time will throttle requests to the backendserver while the client "warms up".</p><p>The default value is 60s.</p><example><cluster id="app-tier"> <client-warmup-time>60s</client-warmup-time> <srun id="app-a" host="192.168.0.10"/> <srun id="app-b" host="192.168.0.11"/></cluster></example></s2><s2 title="client-max-idle-time"><p>client-max-idle-time is a renaming of live-time. It's themaximum time the socket will stay in the idle pool for a load balancerbefore it's removed.</p></s2><s2 title="client-fail-recover-time"><p>client-max-idle-time is a renaming of dead-time. It's thetime the load balancer will skip a dead backend server before retrying.</p></s2></s1><s1 title="Hessian"><s2 title="Hessian 2.0 Draft"><p>An early draft of <a href="../doc/hessian-2.0-spec.xtp">Hessian2.0</a> protocol is available.</p><p>Hessian 2.0 provides a number of compact bytecodes to reduce thesize of serialized messages.
