Non-clustered, non-persistent, in-memory-only is the default style of session management.
In previous versions of Jetty this was referred to as "hash" sessions, as they were stored in a HashMap
in memory.
This is delivered by a combination of the DefaultSessionCache
(to keep sessions in memory) and a NullSessionDataStore
(to avoid session persistence).
If you do nothing, Jetty will instantiate one of each of these objects for each context at startup time using hard-coded defaults.
To explicitly set up non-persisted sessions using modules, use both the session-cache-hash
and the session-store-null
modules.
Enabling the modules allows you to configure behavior - see the L1 Session Cache for detailed information on configuration options for the DefaultSessionCache
.
The NullSessionDataStore
has no customizable options.
