Plack::Session::Store(3) Basic in-memory session store


use Plack::Builder;
use Plack::Middleware::Session;
use Plack::Session::Store;
my $app = sub {
return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];

enable 'Session'; # this is the defalt store


This is a very basic in-memory session data store. It is volatile storage and not recommended for multiprocessing environments. However it is very useful for development and testing.

This should be considered the store ``base'' class (although subclassing is not a requirement) and defines the spec for all Plack::Session::Store::* modules. You will only need to override a couple methods if you do subclass. See the other Plack::Session::Store::* for examples of this.


new ( %params )
No parameters are expected to this constructor.

Session Data Management

These methods fetch data from the session storage. It's designed to store or delete multiple keys at a time.
fetch ( $session_id )
store ( $session_id, $session )

Storage Management

remove ( $session_id )
This method is called by the Plack::Session "expire" method and is used to remove any session data.


All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
