+ <!-- Defines a cluster for this node,
+ By defining this element, means that every manager will be changed.
+ So when running a cluster, only make sure that you have webapps in
there
+ that need to be clustered and remove the other ones.
+ A cluster has the following parameters:
+
+ className = the fully qualified name of the cluster class
+
+ name = a descriptive name for your cluster, can be anything
+
+ debug = the debug level, higher means more output
+
+ mcastAddr = the multicast address, has to be the same for all the nodes
+
+ mcastPort = the multicast port, has to be the same for all the nodes
+
+ mcastFrequency = the number of milliseconds in between sending a "I'm
alive" heartbeat
+
+ mcastDropTime = the number a milliseconds before a node is considered
"dead" if no heartbeat is received
+
+ tcpThreadCount = the number of threads to handle incoming replication
requests, optimal would be the same amount of threads as nodes
+
+ tcpListenAddress = the listen address (bind address) for TCP cluster
request on this host,
+ in case of multiple ethernet cards.
+ auto means that address becomes
+ InetAddress.getLocalHost().getHostAddress()
+
+ tcpListenPort = the tcp listen port
+
+ tcpSelectorTimeout = the timeout (ms) for the Selector.select() method
in case the OS
+ has a wakup bug in java.nio. Set to 0 for no
timeout
+
+ printToScreen = true means that managers will also print to std.out
+
+ expireSessionsOnShutdown = true means that
+
+ useDirtyFlag = true means that we only replicate a session after
setAttribute,removeAttribute has been called.
+ false means to replicate the session after each request.
+ false means that replication would work for the
following piece of code:
+ <%
+ HashMap map = (HashMap)session.getAttribute("map");
+ map.put("key","value");
+ %>

+ When configuring for clustering, you also add in a valve to catch all
the requests
+ coming in, at the end of the request, the session may or may not be
replicated.
+ A session is replicated if and only if all the conditions are met:
+ 1. useDirtyFlag is true or setAttribute or removeAttribute has been
called AND
+ 2. a session exists (has been created)
+ 3. the request is not trapped by the "filter" attribute
+
+ The filter attribute is to filter out requests that could not modify
the session,
+ hence we don't replicate the session after the end of this request.
+ The filter is negative, ie, anything you put in the filter, you mean to
filter out,
+ ie, no replication will be done on requests that match one of the
filters.
+ The filter attribute is delimited by ;, so you can't escape out ; even
if you wanted to.
+
+ filter=".*\.gif;.*\.js;" means that we will not replicate the session
after requests with the URI
+ ending with .gif and .js are intercepted.
