NAME

       Dancer::Session::YAML - YAML-file-based session backend for Dancer

DESCRIPTION

       This module implements a session engine based on YAML files. Session are stored in a session_dir as YAML files. The idea behind this module
       was to provide a transparent session storage for the developer.

       This backend is intended to be used in development environments, when looking inside a session can be useful.

       It's not recommended to use this session engine in production environments.

CONFIGURATION

       The setting session should be set to "YAML" in order to use this session engine in a Dancer application.

       Files will be stored to the value of the setting "session_dir", whose default value is "appdir/sessions".

       Here is an example configuration that use this session engine and stores session files in /tmp/dancer-sessions

	   session: "YAML"
	   session_dir: "/tmp/dancer-sessions"

METHODS

   reset
       to avoid checking if the sessions directory exists everytime a new session is created, this module maintains a cache of session directories
       it has already created. "reset" wipes this cache out, forcing a test for existence of the sessions directory next time a session is
       created. It takes no argument.

       This is particulary useful if you want to remove the sessions directory on the system where your app is running, but you want this session
       engine to continue to work without having to restart your application.

DEPENDENCY

       This module depends on YAML.

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.
