=head1 DESCRIPTION This module implements Dancer 2 session engine based on L<Sereal> files. This backend can be used in single-machine production environments, but two things should be kept in mind: The content of the session files is not encrypted or protected in anyway and old session files should be purged by a CRON job. =head1 CONFIGURATION The setting B<session> should be set to C<Sereal> in order to use this session engine in a Dancer2 application. Files will be stored to the value of the setting C<session_dir>, whose default value is C<appdir/sessions>. Arguments for the L<Sereal::Encoder> and L<Sereal::Decoder> objects can be given via the C<encoder_args> and C<decoder_args>. If not provided, they default to C<< snappy => 1, croak_on_bless =>1 >> and C<< refuse_objects => 1, validate_utf8 => 1 >>, respectively. Here is an example configuration that use this session engine and stores session files in /tmp/dancer-sessions session: "Sereal" engines: session: Sereal: session_dir: "/tmp/dancer-sessions" encoder_args: snappy: 1 croak_on_bless: 1 decoder_args: refuse_objects: 1 validate_utf8: 1
