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.
