68 | =head1 DESCRIPTION |
69 | |
3d92cf47 |
70 | This is a Plack Middleware component for session management. By |
71 | default it will use cookies to keep session state and store data |
72 | in memory. This distribution comes also comes with other state |
73 | and store solutions. |
74 | |
75 | =head2 State |
76 | |
77 | =over 4 |
78 | |
79 | =item L<Plack::Session::State> |
80 | |
81 | This will maintain session state by passing the session through |
82 | the request params. It does not do this automatically though, |
83 | you are responsible for passing the session param. |
84 | |
85 | =item L<Plack::Session::State::Cookie> |
86 | |
87 | This will maintain session state using browser cookies. |

92 | |
93 | =over 4 |
94 | |
95 | =item L<Plack::Session::Store> |
96 | |
97 | This is your basic in-memory session data store. It is volatile storage |
98 | and not recommended for multiprocessing environments. However it is |
99 | very useful for development and testing. |
100 | |
101 | =item L<Plack::Session::Store::File> |
102 | |
103 | This will persist session data in a file. By default it uses |
104 | L<Storable> but it can be configured to have a custom serializer and |
105 | deserializer. |
106 | |
107 | =item L<Plack::Session::Store::CHI> |
108 | |
109 | This will persist session data using the L<CHI> module. This |
110 | offers a lot of flexibility due to the many excellent L<CHI> |
111 | drivers available. |
112 | |
113 | =item L<Plack::Session::Store::Null> |
114 | |
115 | Sometimes you don't care about storing session data, in that case |
116 | you can use this noop module. |
