NAME

       Catalyst::Plugin::Session::State - Base class for session state preservation plugins.

SYNOPSIS

           package Catalyst::Plugin::Session::State::MyBackend;
           use base qw/Catalyst::Plugin::Session::State/;

DESCRIPTION

       This class doesn't actually provide any functionality, but when the "Catalyst::Plugin::Session" module
       sets up it will check to see that "YourApp->isa("Catalyst::Plugin::Session::State")".

       When you write a session state plugin you should subclass this module this reason only.

WRITING STATE PLUGINS

       To write a session state plugin you usually need to extend two methods:

       prepare_(action|cookies|whatever)
           Set "sessionid" (accessor) at prepare time using data in the request.

           Note  that  this  must  happen  before  other  "prepare_action" instances, in order to get along with
           Catalyst::Plugin::Session. Overriding "prepare_cookies" is probably the stablest approach.

       finalize
           Modify the response at to include the session ID if "sessionid" is defined, using whatever scheme you
           use. For example, set a cookie,

perl v5.20.2                                       2015-01-26              Catalyst::Plugin::Session::State(3pm)
