-
-         By default, a non-SSL HTTP/1.1 Connector is established on port 8080.

-         instructions):
-         * If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or

-             $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA  (Unix)

-
-         By default, DNS lookups are enabled when a web application calls
-         request.getRemoteHost().  This can have an adverse impact on
-         performance, so you can disable it by setting the
-         "enableLookups" attribute to "false".  When DNS lookups are disabled,
-         request.getRemoteHost() will return the String version of the
-         IP address of the remote client.

-           headers and cookies that were sent, for all requests received by
-           this instance of Tomcat.  If you care only about requests to a
-           particular virtual host, or a particular application, nest this
-           element inside the corresponding <Host> or <Context> entry instead.
-
-           For a similar mechanism that is portable to all Servlet 2.4
-           containers, check out the "RequestDumperFilter" Filter in the
-           example application (the source for this filter may be found in
-           "$CATALINA_HOME/webapps/examples/WEB-INF/classes/filters").
-
-           Note that this Valve uses the platform's default character encoding.
-           This may cause problems for developers in another encoding, e.g.
-           UTF-8.  Use the RequestDumperFilter instead.
-
-           Also note that enabling this Valve will write a ton of stuff to your
-           logs.  They are likely to grow quite large.  This extensive log writing
-           will definitely slow down your server.
-
-           Request dumping is disabled by default.  Uncomment the following
-           element to enable it. -->

-             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
-
-             clusterName = a descriptive name for your cluster, can be anything

-
-             mcastPort = the multicast port, has to be the same for all the nodes
-             
-             mcastBindAddress = bind the multicast socket to a specific address
-             
-             mcastTTL = the multicast TTL if you want to limit your broadcast
-             
-             mcastSoTimeout = the multicast readtimeout 
-
-             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

-                            false means to replicate the session after each request.
-                            false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)

-                               * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
-                               * Synchronous means that the thread that executes the request, is also the
-                               thread the replicates the data to the other nodes, and will not return until all
-                               nodes have received the information.
-                               * Asynchronous means that there is a specific 'sender' thread for each cluster node,
-                               so the request thread will queue the replication request into a "smart" queue,
-                               and then return to the client.
-                               The "smart" queue is a queue where when a session is added to the queue, and the same session
-                               already exists in the queue from a previous request, that session will be replaced
-                               in the queue instead of replicating two requests. This almost never happens, unless there is a 
-                               large network delay.
-        -->             
-        <!--
-            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.

-            The deployer element can be used to deploy apps cluster wide.
-            Currently the deployment only deploys/undeploys to working members in the cluster
-            so no WARs are copied upons startup of a broken node.
-            The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
-            When a new war file is added the war gets deployed to the local instance,
-            and then deployed to the other instances in the cluster.
-            When a war file is deleted from the watchDir the war is undeployed locally

-         "enableLookups" attribute to "false".  When DNS lookups are disabled,
-         request.getRemoteHost() will return the String version of the

-
-             tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes 
-

-                                in case of multiple ethernet cards.
-                                auto means that address becomes

-                               * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
-                               * Synchronous means that the thread that executes the request, is also the
-                               thread the replicates the data to the other nodes, and will not return until all
-                               nodes have received the information.
-                               * Asynchronous means that there is a specific 'sender' thread for each cluster node,
-                               so the request thread will queue the replication request into a "smart" queue,
-                               and then return to the client.
-                               The "smart" queue is a queue where when a session is added to the queue, and the same session
-                               already exists in the queue from a previous request, that session will be replaced
-                               in the queue instead of replicating two requests. This almost never happens, unless there is a 
-                               large network delay.

-            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

-         "enableLookups" attribute to "false".  When DNS lookups are disabled,
-         request.getRemoteHost() will return the String version of the

-
-             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

This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
-                               * Synchronous means that the thread that executes the request, is also the
-                               thread the replicates the data to the other nodes, and will not return until all
-                               nodes have received the information.
-                               * Asynchronous means that there is a specific 'sender' thread for each cluster node,
-                               so the request thread will queue the replication request into a "smart" queue,
-                               and then return to the client.
-                               The "smart" queue is a queue where when a session is added to the queue, and the same session
-                               already exists in the queue from a previous request, that session will be replaced
-                               in the queue instead of replicating two requests. This almost never happens, unless there is a 
-                               large network delay.

-            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.

-            The deployer element can be used to deploy apps cluster wide.
-            Currently the deployment only deploys/undeploys to working members in the cluster
-            so no WARs are copied upons startup of a broken node.
-            The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
-            When a new war file is added the war gets deployed to the local instance,
-            and then deployed to the other instances in the cluster.
-            When a war file is deleted from the watchDir the war is undeployed locally 
-            and cluster wide
