Obviously sent a wrong file contents earlier!!!

 

Here is the actual server.xml contents 

 

<!-- Example Server Configuration File -->

<!-- Note that component elements are nested corresponding to their

     parent-child relationships with each other -->

<!-- A "Server" is a singleton element that represents the entire JVM,

     which may contain one or more "Service" instances.  The Server

     listens for a shutdown command on the indicated port.

 

     Note:  A "Server" is not itself a "Container", so you may not

     define subcomponents such as "Valves" or "Loggers" at this level.

 -->

<Server port="8005" shutdown="SHUTDOWN">

       <!-- Comment these entries out to disable JMX MBeans support used for the 

       administration web application -->

       <!-- A "Service" is a collection of one or more "Connectors" that share

       a single "Container" (and therefore the web applications visible

       Note:  A "Service" is not itself a "Container", so you may not

       define subcomponents such as "Valves" or "Loggers" at this level.

       <!-- Define the Tomcat Stand-Alone Service -->

       <Service name="Catalina">

             <!-- A "Connector" represents an endpoint by which requests are received

         and responses are returned.  Each Connector passes requests on to the

         associated "Container" (normally an Engine) for processing.

 

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

         You can also enable an SSL HTTP/1.1 Connector on port 8443 by

         following the instructions below and uncommenting the second Connector

         entry.  SSL support requires the following steps (see the SSL Config

         HOWTO in the Tomcat 5 documentation bundle for more detailed

         instructions):

         * If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or

           later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".

         * Execute:

             %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)

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

           with a password value of "changeit" for both the certificate and

           the keystore itself.

 

         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.

             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

 

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

 

             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

             

             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

 

             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: (only for SimpleTcpReplicationManager)

                            <%

                            HashMap map = (HashMap)session.getAttribute("map");

                            map.put("key","value");

                            %>

             replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.

                               * 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 

            and cluster wide

In one of those exceedingly rare moments where I agree with the previous poster can you cut
and paste your entire server.xml into the message body?

Also which browser version are you testing with?

 

Thx,

You don't seem to be providing much real information in any of your

posts.  At least tell us the exact Tomcat level and provide your actual

relevant config files.  (Your above sample, using <connector> rather

than <Connector>, is obviously not correct.)  In this instance, also

include the name and level of the browser you're using; there are known

issues in IE6 about mishandling redirects.  You might want to do a

packet capture so you can differentiate between what Tomcat's sending

and what the browser is deciding to interpret it as.
