* <p/>
* This filter supports the following {@code &lt;init-param&gt;} values:
* <ul>
* <li>{@code use-client}: When enabled, a {@link com.hazelcast.client.HazelcastClient HazelcastClient} is
* used to connect to the cluster, rather than joining as a full node. (Default: {@code false})</li>
* <li>{@code config-location}: Specifies the location of an XML configuration file that can be used to
* initialize the {@link HazelcastInstance} (Default: None; the {@link HazelcastInstance} is initialized
* using its own defaults)</li>
* <li>{@code client-config-location}: Specifies the location of an XML configuration file that can be
* used to initialize the {@link HazelcastInstance}. <i>This setting is only checked when {@code use-client}
* is set to {@code true}.</i> (Default: Falls back on {@code config-location})</li>
* <li>{@code instance-name}: Names the {@link HazelcastInstance}. This can be used to reference an already-
* initialized {@link HazelcastInstance} in the same JVM (Default: The configured instance name, or a
* generated name if the configuration does not specify a value)</li>
* <li>{@code shutdown-on-destroy}: When enabled, shuts down the {@link HazelcastInstance} when the filter is
* destroyed (Default: {@code true})</li>
* <li>{@code map-name}: Names the {@link IMap} the filter should use to persist session details (Default:
* {@code "_web_" + ServletContext.getServletContextName()}; e.g. "_web_MyApp")</li>
* <li>{@code session-ttl-seconds}: Sets the {@link MapConfig#setTimeToLiveSeconds(int) time-to-live} for
* the {@link IMap} used to persist session details (Default: Uses the existing {@link MapConfig} setting
* for the {@link IMap}, which defaults to infinite)</li>
* <li>{@code sticky-session}: When enabled, optimizes {@link IMap} interactions by assuming individual sessions
* are only used from a single node (Default: {@code true})</li>
* <li>{@code deferred-write}: When enabled, optimizes {@link IMap} interactions by only writing session attributes
* at the end of a request. This can yield significant performance improvements for session-heavy applications
* (Default: {@code false})</li>
* <li>{@code cookie-name}: Sets the name for the Hazelcast session cookie (Default:
* {@link #HAZELCAST_SESSION_COOKIE_NAME "hazelcast.sessionId"}</li>
* <li>{@code cookie-domain}: Sets the domain for the Hazelcast session cookie (Default: {@code null})</li>
* <li>{@code cookie-secure}: When enabled, indicates the Hazelcast session cookie should only be sent over
* secure protocols (Default: {@code false})</li>
* <li>{@code cookie-http-only}: When enabled, marks the Hazelcast session cookie as "HttpOnly", indicating
* it should not be available to scripts (Default: {@code false})
* <ul>
* <li>{@code cookie-http-only} requires a Servlet 3.0-compatible container, such as Tomcat 7+ or Jetty 8+</li>
