# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2/> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding05/09/2008
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "C:/Program Files/Apache Software Foundation/Apache2.2" will be interpreted by the
# server as "C:/Program Files/Apache Software Foundation/Apache2.2/logs/foo.log".
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which Apache.exe is located
# will be used by default.  It is recommended that you always supply
# an explicit drive letter in absolute paths, however, to avoid
# confusion.
#

# ThreadsPerChild: constant number of worker threads in the server process
# MaxRequestsPerChild: maximum  number of requests a server process serves
ThreadsPerChild 250
MaxRequestsPerChild  0

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "C:/Program Files/Apache Software Foundation/Apache2.2"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)

#Listen 12.34.56.78:80

# 'Main' server configuration

# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition.  These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.

    # Example:
    # Redirect permanent /foo http://127.0.0.1/bar

    #
    # Alias: Maps web paths into filesystem paths and is used to

    # Example:
    # Alias /webpath /full/filesystem/path
    #
    # If you include a trailing / on /webpath then the server will

    # ScriptAlias: This controls which directories contain server scripts. 
    # ScriptAliases are essentially the same as Aliases, except that

# 
# Apache parses all CGI scripts for the shebang line by default.
# This comment line, the first line of the script, consists of the symbols
# pound (#) and exclamation (!) followed by the path of the program that 
# can execute this specific script.  For a perl script, with perl.exe in
# the C:\Program Files\Perl directory, the shebang line should be:

   #!c:/program files/perl/perl

# Note you _must_not_ indent the actual shebang line, and it must be the
# first line of the file.  Of course, CGI processing must be enabled by 
# the appropriate ScriptAlias or Options ExecCGI directives for the files 
# or directory in question.
#
# However, Apache on Windows allows either the Unix behavior above, or can
# use the Registry to match files by extention.  The command to execute 
# a file of this type is retrieved from the registry by the same method as 
# the Windows Explorer would use to handle double-clicking on a file.
# These script actions can be configured from the Windows Explorer View menu, 
# 'Folder Options', and reviewing the 'File Types' tab.  Clicking the Edit
# button allows you to modify the Actions, of which Apache 1.3 attempts to
# perform the 'Open' Action, and failing that it will try the shebang line.
# This behavior is subject to change in Apache release 2.0.
#
# Each mechanism has it's own specific security weaknesses, from the means
# to run a program you didn't intend the website owner to invoke, and the
# best method is a matter of great debate.
#
# To enable the this Windows specific behavior (and therefore -disable- the
# equivilant Unix behavior), uncomment the following directive:
#
#ScriptInterpreterSource registry
#
# The directive above can be placed in individual <Directory> blocks or the
# .htaccess file, with either the 'registry' (Windows behavior) or 'script' 
# (Unix behavior) option, and will override this server default option.
#

#
# DefaultType: the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value.  If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.

    # TypesConfig points to the file containing the list of mappings from
    # filename extension to MIME-type.

    # AddType allows you to add to or override the MIME configuration
    # file specified in TypesConfig for specific file types.

    #
    #AddEncoding x-compress .Z
    #AddEncoding x-gzip .gz .tgz

    AddType application/x-compress .Z
    AddType application/x-gzip .gz .tgz

    #
    # AddHandler allows you to map certain file extensions to "handlers":
    # actions unrelated to filetype. These can be either built into the server
    # or added with the Action directive (see below)
    #
    # To use CGI scripts outside of ScriptAliased directories:
    # (You will also need to add "ExecCGI" to the "Options" directive.)

         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.

        <!-- 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

             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

             mcastBindAddr = 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
