NAME

       Plack::Session::Store - Basic in-memory session store

SYNOPSIS

	 use Plack::Builder;
	 use Plack::Middleware::Session;
	 use Plack::Session::Store;

	 my $app = sub {
	     return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
	 };

	 builder {
	     enable 'Session'; # this is the defalt store
	     $app;
	 };

DESCRIPTION

       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.

METHODS

       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.

BUGS

       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.

NAME

       Plack::Session::Store::DBI - DBI-based session store

SYNOPSIS

	 use Plack::Builder;
	 use Plack::Middleware::Session;
	 use Plack::Session::Store::DBI;

	 my $app = sub {
	     return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
	 };

	 builder {
	     enable 'Session',
		 store => Plack::Session::Store::DBI->new(
		     dbh => DBI->connect( @connect_args )
		 );
	     $app;
	 };

	 # set get_dbh callback for ondemand

	 builder {
	     enable 'Session',
		 store => Plack::Session::Store::DBI->new(
		     get_dbh => sub { DBI->connect( @connect_args ) }
		 );
	     $app;
	 };

	 # with custom serializer/deserializer

	 builder {
	     enable 'Session',
		 store => Plack::Session::Store::DBI->new(
		     dbh => DBI->connect( @connect_args )
		     # YAML takes it's args the opposite order
		     serializer   => sub { YAML::DumpFile( reverse @_ ) },
		     deserializer => sub { YAML::LoadFile( @_ ) },
		 );
	     $app;
	 };

DESCRIPTION

       This implements a DBI based storage for session data. By default it will use Storable and MIME::Base64 to serialize and deserialize the
       data, but this can be configured easily.

       This is a subclass of Plack::Session::Store and implements its full interface.

SESSION TABLE SCHEMA

       Your session table must have at least the following schema structure:

	   CREATE TABLE sessions (
	       id	    CHAR(72) PRIMARY KEY,
	       session_data TEXT
	   );

       Note that MySQL TEXT fields only store 64KB, so if your session data will exceed that size you'll want to move to MEDIUMTEXT, MEDIUMBLOB,
       or larger.
