NAME¶

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

    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.

finalize

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