NAME

       Plack::Session::Store::File - Basic file-based session store

SYNOPSIS

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

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

         builder {
             enable 'Session',
                 store => Plack::Session::Store::File->new(
                     dir => '/path/to/sessions'
                 );
             $app;
         };

         # with custom serializer/deserializer

         builder {
             enable 'Session',
                 store => Plack::Session::Store::File->new(
                     dir          => '/path/to/sessions',
                     # YAML takes it's args the opposite order
                     serializer   => sub { YAML::DumpFile( reverse @_ ) },
                     deserializer => sub { YAML::LoadFile( @_ ) },
                 );
             $app;
         };

DESCRIPTION

       This implements a basic file based storage for session data. By default it will use
       Storable 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.

METHODS

       new ( %params )
           The %params can include dir, serializer and deserializer options. It will check to be
           sure that the dir is writeable for you.

       dir This is the directory to store the session data files in, if nothing is provided then
           "/tmp" is used.

       serializer
           This is a CODE reference that implements the serialization logic.  The CODE ref gets
           two arguments, the $value, which is a HASH reference to be serialized, and the
           $file_path to save it to.  It is not expected to return anything.

       deserializer
           This is a CODE reference that implements the deserialization logic.  The CODE ref gets
           one argument, the $file_path to load the data from. It is expected to return a HASH
           reference.

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.
