-    <!--
-    CacheManager Configuration
-    ==========================
-    An ehcache.xml corresponds to a single CacheManager.
-    
-    See instructions below or the ehcache schema (ehcache.xsd) on how to configure.
-
-    System property tokens can be specified in this file which are replaced when the configuration
-    is loaded. For example multicastGroupPort=${multicastGroupPort} can be replaced with the
-    System property either from an environment variable or a system property specified with a
-    command line switch such as -DmulticastGroupPort=4446.
-
-    DiskStore configuration
-    =======================
-
-    The diskStore element is optional. To turn off disk store path creation, comment out the diskStore
-    element below.
-
-    Configure it if you have overflowToDisk or diskPersistent enabled for any cache.
-
-    If it is not configured, and a cache is created which requires a disk store, a warning will be
-     issued and java.io.tmpdir will automatically be used.
-
-    diskStore has only one attribute - "path". It is the path to the directory where
-    .data and .index files will be created.
-
-    If the path is one of the following Java System Property it is replaced by its value in the
-    running VM. For backward compatibility these are not specified without being enclosed in the ${token}
-    replacement syntax.
-
-    The following properties are translated:
-    * user.home - User's home directory
-    * user.dir - User's current working directory
-    * java.io.tmpdir - Default temp file path
-    * ehcache.disk.store.dir - A system property you would normally specify on the command line
-      e.g. java -Dehcache.disk.store.dir=/u01/myapp/diskdir ...
-
-    Subdirectories can be specified below the property e.g. java.io.tmpdir/one
-
-    -->
-    <diskStore path="java.io.tmpdir"/>
-
-    <!--
-    CacheManagerEventListener
-    =========================
-    Specifies a CacheManagerEventListenerFactory which is notified when Caches are added
-    or removed from the CacheManager.
-
-    The attributes of CacheManagerEventListenerFactory are:
-    * class - a fully qualified factory class name
-    * properties - comma separated properties having meaning only to the factory.
-
-    Sets the fully qualified class name to be registered as the CacheManager event listener.
-
-    The events include:
-    * adding a Cache
-    * removing a Cache
-
-    Callbacks to listener methods are synchronous and unsynchronized. It is the responsibility
-    of the implementer to safely handle the potential performance and thread safety issues
-    depending on what their listener is doing.
-
-    If no class is specified, no listener is created. There is no default.

-    <cacheManagerEventListenerFactory class="" properties=""/>
-
-
-    <!--
-    CacheManagerPeerProvider
-    ========================
-    (For distributed operation)
-
-    Specifies a CacheManagerPeerProviderFactory which will be used to create a
-    CacheManagerPeerProvider, which discovers other CacheManagers in the cluster.
-
-    One or more providers can be configured. The first one in the ehcache.xml is the default, which is used
-    for replication and bootstrapping.
-
-    The attributes of cacheManagerPeerProviderFactory are:
-    * class - a fully qualified factory class name
-    * properties - comma separated properties having meaning only to the factory.
-
-    Providers are available for RMI, JGroups and JMS as shown following.
-
-    RMICacheManagerPeerProvider
-    +++++++++++++++++++++++++++
-
-    Ehcache comes with a built-in RMI-based distribution system with two means of discovery of
-    CacheManager peers participating in the cluster:
-    * automatic, using a multicast group. This one automatically discovers peers and detects
-      changes such as peers entering and leaving the group
-    * manual, using manual rmiURL configuration. A hardcoded list of peers is provided at
-      configuration time.
-
-    Configuring Automatic Discovery:
-    Automatic discovery is configured as per the following example:
-    <cacheManagerPeerProviderFactory
-                        class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
-                        properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1,
-                                    multicastGroupPort=4446, timeToLive=32"/>
-
-    Valid properties are:
-    * peerDiscovery (mandatory) - specify "automatic"
-    * multicastGroupAddress (mandatory) - specify a valid multicast group address
-    * multicastGroupPort (mandatory) - specify a dedicated port for the multicast heartbeat
-      traffic
-    * timeToLive - specify a value between 0 and 255 which determines how far the packets will
-      propagate.
-
-      By convention, the restrictions are:
-      0   - the same host
-      1   - the same subnet
-      32  - the same site
-      64  - the same region
-      128 - the same continent
-      255 - unrestricted
-
-    Configuring Manual Discovery:
-    Manual discovery is configured as per the following example:
-    <cacheManagerPeerProviderFactory class=
-                          "net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
-                          properties="peerDiscovery=manual,
-                          rmiUrls=//server1:40000/sampleCache1|//server2:40000/sampleCache1
-                          | //server1:40000/sampleCache2|//server2:40000/sampleCache2"
-                          propertySeparator="," />
-
-    Valid properties are:
-    * peerDiscovery (mandatory) - specify "manual"
-    * rmiUrls (mandatory) - specify a pipe separated list of rmiUrls, in the form
-                            //hostname:port
-
-    The hostname is the hostname of the remote CacheManager peer. The port is the listening
-    port of the RMICacheManagerPeerListener of the remote CacheManager peer.
-    
-    JGroupsCacheManagerPeerProvider
-    +++++++++++++++++++++++++++++++
-    <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.jgroups.JGroupsCacheManagerPeerProviderFactory"
-                                     properties="connect=UDP(mcast_addr=231.12.21.132;mcast_port=45566;ip_ttl=32;

-                                     propertySeparator="::"
-            />
-     The only property necessary is the connect String used by jgroups to configure itself. Refer to the Jgroups documentation for explanation
-     of all the protocols. The example above uses UDP multicast. If the connect property is not specified the default JGroups connection will be
-     used.

-    <cacheManagerPeerProviderFactory
-            class="net.sf.ehcache.distribution.jms.JMSCacheManagerPeerProviderFactory"
-            properties="..."
-            propertySeparator=","
-            />
-
-    The JMS PeerProviderFactory uses JNDI to maintain message queue independence. Refer to the manual for full configuration
-    examples using ActiveMQ and Open Message Queue.
-
-    Valid properties are:
-    * initialContextFactoryName (mandatory) - the name of the factory used to create the message queue initial context.
-    * providerURL (mandatory) - the JNDI configuration information for the service provider to use.
-    * replicationTopicConnectionFactoryBindingName (mandatory) - the JNDI binding name for the TopicConnectionFactory

-    CacheManagerPeerListener
-    ========================
-    (Enable for distributed operation)
-
-    Specifies a CacheManagerPeerListenerFactory which will be used to create a
-    CacheManagerPeerListener, which
-    listens for messages from cache replicators participating in the cluster.
-
-    The attributes of cacheManagerPeerListenerFactory are:
-    class - a fully qualified factory class name
-    properties - comma separated properties having meaning only to the factory.
-
-    Ehcache comes with a built-in RMI-based distribution system. The listener component is
-    RMICacheManagerPeerListener which is configured using
-    RMICacheManagerPeerListenerFactory. It is configured as per the following example:
-
-    <cacheManagerPeerListenerFactory
-        class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
-        properties="hostName=fully_qualified_hostname_or_ip,

-                    remoteObjectPort=40002,
-                    socketTimeoutMillis=120000"
-                    propertySeparator="," />
-
-    All properties are optional. They are:
-    * hostName - the hostName of the host the listener is running on. Specify
-      where the host is multihomed and you want to control the interface over which cluster
-      messages are received. Defaults to the host name of the default interface if not
-      specified.
-    * port - the port the RMI Registry listener listens on. This defaults to a free port if not specified.
-    * remoteObjectPort - the port number on which the remote objects bound in the registry receive calls.
-                         This defaults to a free port if not specified.
-    * socketTimeoutMillis - the number of ms client sockets will stay open when sending
-      messages to the listener. This should be long enough for the slowest message.
-      If not specified it defaults to 120000ms.
-
-    -->
-    <cacheManagerPeerListenerFactory
-            class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"/>
-
-
-    <!--
-    Cache configuration
-    ===================
-
-    The following attributes are required.
-
-    name:
-    Sets the name of the cache. This is used to identify the cache. It must be unique.
-
-    maxElementsInMemory:
-    Sets the maximum number of objects that will be created in memory
-
-	maxElementsOnDisk:
-    Sets the maximum number of objects that will be maintained in the DiskStore
-	The default value is zero, meaning unlimited.
-
-    eternal:
-    Sets whether elements are eternal. If eternal,  timeouts are ignored and the
-    element is never expired.
-
-    overflowToDisk:
-    Sets whether elements can overflow to disk when the memory store
-    has reached the maxInMemory limit.
-
-    The following attributes and elements are optional.
-
-    timeToIdleSeconds:
-    Sets the time to idle for an element before it expires.
-    i.e. The maximum amount of time between accesses before an element expires
-    Is only used if the element is not eternal.
-    Optional attribute. A value of 0 means that an Element can idle for infinity.
-    The default value is 0.
-
-    timeToLiveSeconds:
-    Sets the time to live for an element before it expires.
-    i.e. The maximum time between creation time and when an element expires.
-    Is only used if the element is not eternal.
-    Optional attribute. A value of 0 means that and Element can live for infinity.
-    The default value is 0.
-
-    diskPersistent:
-    Whether the disk store persists between restarts of the Virtual Machine.
-    The default value is false.
-
-    diskExpiryThreadIntervalSeconds:
-    The number of seconds between runs of the disk expiry thread. The default value
-    is 120 seconds.
-
-    diskSpoolBufferSizeMB:
-    This is the size to allocate the DiskStore for a spool buffer. Writes are made
-    to this area and then asynchronously written to disk. The default size is 30MB.
-    Each spool buffer is used only by its cache. If you get OutOfMemory errors consider
-    lowering this value. To improve DiskStore performance consider increasing it. Trace level
-    logging in the DiskStore will show if put back ups are occurring.
-
-    clearOnFlush:
-    whether the MemoryStore should be cleared when flush() is called on the cache.
-    By default, this is true i.e. the MemoryStore is cleared.
-
-    memoryStoreEvictionPolicy:
-    Policy would be enforced upon reaching the maxElementsInMemory limit. Default
-    policy is Least Recently Used (specified as LRU). Other policies available -
-    First In First Out (specified as FIFO) and Less Frequently Used
-    (specified as LFU)
-
-    Cache elements can also contain sub elements which take the same format of a factory class
-    and properties. Defined sub-elements are:
-
-    * cacheEventListenerFactory - Enables registration of listeners for cache events, such as
-      put, remove, update, and expire.
-
-    * bootstrapCacheLoaderFactory - Specifies a BootstrapCacheLoader, which is called by a
-      cache on initialisation to prepopulate itself.
-
-    * cacheExtensionFactory - Specifies a CacheExtension, a generic mechansim to tie a class
-      which holds a reference to a cache to the cache lifecycle.
-
-    * cacheExceptionHandlerFactory - Specifies a CacheExceptionHandler, which is called when
-      cache exceptions occur.
-
-    * cacheLoaderFactory - Specifies a CacheLoader, which can be used both asynchronously and
-      synchronously to load objects into a cache. More than one cacheLoaderFactory element
-      can be added, in which case the loaders form a chain which are executed in order. If a
-      loader returns null, the next in chain is called.
-
-    RMI Cache Replication
-    +++++++++++++++++++++
-
-    Each cache that will be distributed needs to set a cache event listener which replicates
-    messages to the other CacheManager peers. For the built-in RMI implementation this is done
-    by adding a cacheEventListenerFactory element of type RMICacheReplicatorFactory to each
-    distributed cache's configuration as per the following example:
-
-    <cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
-         properties="replicateAsynchronously=true,
-         replicatePuts=true,
-         replicatePutsViaCopy=false,
-         replicateUpdates=true,
-         replicateUpdatesViaCopy=true,
-         replicateRemovals=true
-         asynchronousReplicationIntervalMillis=<number of milliseconds"
-         propertySeparator="," />
-
-    The RMICacheReplicatorFactory recognises the following properties:
-
-    * replicatePuts=true|false - whether new elements placed in a cache are
-      replicated to others. Defaults to true.
-
-    * replicatePutsViaCopy=true|false - whether the new elements are
-      copied to other caches (true), or whether a remove message is sent. Defaults to true.  
-
-    * replicateUpdates=true|false - whether new elements which override an
-      element already existing with the same key are replicated. Defaults to true.
-
-    * replicateRemovals=true - whether element removals are replicated. Defaults to true.
-
-    * replicateAsynchronously=true | false - whether replications are
-      asynchronous (true) or synchronous (false). Defaults to true.
-
-    * replicateUpdatesViaCopy=true | false - whether the new elements are
-      copied to other caches (true), or whether a remove message is sent. Defaults to true.
-
-    * asynchronousReplicationIntervalMillis=<number of milliseconds> - The asynchronous
-      replicator runs at a set interval of milliseconds. The default is 1000. The minimum
-      is 10. This property is only applicable if replicateAsynchronously=true
-
-
-    JGroups Replication
-    +++++++++++++++++++
-
-	For the Jgroups replication this is done with:
-	<cacheEventListenerFactory class="net.sf.ehcache.distribution.jgroups.JGroupsCacheReplicatorFactory"
-                            properties="replicateAsynchronously=true, replicatePuts=true,
- 							replicateUpdates=true, replicateUpdatesViaCopy=false,
- 							replicateRemovals=true,asynchronousReplicationIntervalMillis=1000"/>
-    This listener supports the same properties as the RMICacheReplicationFactory.
-
-
-    JMS Replication
-    +++++++++++++++
-
-	For JMS-based replication this is done with:
-	<cacheEventListenerFactory
-          class="net.sf.ehcache.distribution.jms.JMSCacheReplicatorFactory"
-          properties="replicateAsynchronously=true,
-                       replicatePuts=true,
-                       replicateUpdates=true,
-                       replicateUpdatesViaCopy=true,
-                       replicateRemovals=true,
-                       asynchronousReplicationIntervalMillis=1000"
-           propertySeparator=","/>
-
-    This listener supports the same properties as the RMICacheReplicationFactory.
-    
-    Cluster Bootstrapping
-    +++++++++++++++++++++
-
-    Bootstrapping a cluster may use a different mechanism to replication. e.g you can mix
-    JMS replication with bootstrap via RMI - just make sure you have the cacheManagerPeerProviderFactory
-    and cacheManagerPeerListenerFactory configured.
-
-    There are two bootstrapping mechanisms: RMI and JGroups.
-
-    RMI Bootstrap
-
-    The RMIBootstrapCacheLoader bootstraps caches in clusters where RMICacheReplicators are
-    used. It is configured as per the following example:
-
-    <bootstrapCacheLoaderFactory
-        class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
-        properties="bootstrapAsynchronously=true, maximumChunkSizeBytes=5000000"
-        propertySeparator="," />
-
-    The RMIBootstrapCacheLoaderFactory recognises the following optional properties:
-
-    * bootstrapAsynchronously=true|false - whether the bootstrap happens in the background
-      after the cache has started. If false, bootstrapping must complete before the cache is
-      made available. The default value is true.
-
-    * maximumChunkSizeBytes=<integer> - Caches can potentially be very large, larger than the
-      memory limits of the VM. This property allows the bootstraper to fetched elements in
-      chunks. The default chunk size is 5000000 (5MB).
-
-    JGroups Bootstrap
-
-    Here is an example of bootstrap configuration using JGroups boostrap:
-
-    <bootstrapCacheLoaderFactory class="net.sf.ehcache.distribution.jgroups.JGroupsBootstrapCacheLoaderFactory"
-                                    properties="bootstrapAsynchronously=true"/>
-
-    The configuration properties are the same as for RMI above. Note that JGroups bootstrap only supports
-    asynchronous bootstrap mode.                                
-
-
-    Cache Exception Handling
-
-    By default, most cache operations will propagate a runtime CacheException on failure. An
-    interceptor, using a dynamic proxy, may be configured so that a CacheExceptionHandler can
-    be configured to intercept Exceptions. Errors are not intercepted.
-
-    It is configured as per the following example:
-
-      <cacheExceptionHandlerFactory class="com.example.ExampleExceptionHandlerFactory"
-                                      properties="logLevel=FINE"/>
-
-    Caches with ExceptionHandling configured are not of type Cache, but are of type Ehcache only,
-    and are not available using CacheManager.getCache(), but using CacheManager.getEhcache().
-
-
-    Cache Loader
-
-    A default CacheLoader may be set which loads objects into the cache through asynchronous and
-    synchronous methods on Cache. This is different to the bootstrap cache loader, which is used
-    only in distributed caching.
-
-    It is configured as per the following example:
-
-        <cacheLoaderFactory class="com.example.ExampleCacheLoaderFactory"
-                                      properties="type=int,startCounter=10"/>
-
-    Cache Extension
-
-    CacheExtensions are a general purpose mechanism to allow generic extensions to a Cache.
-    CacheExtensions are tied into the Cache lifecycle.
-
-    CacheExtensions are created using the CacheExtensionFactory which has a
-    <code>createCacheCacheExtension()</code> method which takes as a parameter a
-    Cache and properties. It can thus call back into any public method on Cache, including, of
-    course, the load methods.
-
-    Extensions are added as per the following example:
-
-         <cacheExtensionFactory class="com.example.FileWatchingCacheRefresherExtensionFactory"
-                             properties="refreshIntervalMillis=18000, loaderTimeout=3000,
-                                         flushPeriod=whatever, someOtherProperty=someValue ..."/>

-    Mandatory Default Cache configuration. These settings will be applied to caches
-    created programmtically using CacheManager.add(String cacheName).

-    -->
-    <defaultCache
-            maxElementsInMemory="10000"
-            eternal="false"
