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 writable 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.

NAME

       Apache::Session::Flex - Specify everything at runtime

SYNOPSIS

	use Apache::Session::Flex;

	tie %hash, 'Apache::Session::Flex', $id, {
	   Store     => 'DB_File',
	   Lock      => 'Null',
	   Generate  => 'MD5',
	   Serialize => 'Storable'
	};

	# or

	tie %hash, 'Apache::Session::Flex', $id, {
	   Store     => 'Postgres',
	   Lock      => 'Null',
	   Generate  => 'MD5',
	   Serialize => 'Base64'
	};

	# you decide!

DESCRIPTION

       This module is an implementation of Apache::Session.  Unlike other implementations, it allows you to specify the backing store, locking
       scheme, ID generator, and data serializer at runtime.  You do this by passing arguments in the usual Apache::Session style (see SYNOPSIS).
       You may use any of the modules included in this distribution, or a module of your own making.  If you wish to use a module of your own
       making, you should make sure that it is available under the Apache::Session package namespace.

USAGE

       You pass the modules you want to use as arguments to the constructor.  The Apache::Session::Whatever part is appended for you: you should
       not supply it.  For example, if you wanted to use MySQL as the backing store, you should give the argument "Store =" 'MySQL'>, and not
       "Store =" 'Apache::Session::Store::MySQL'>.  There are four modules that you need to specify.  Store is the backing store to use.  Lock is
       the locking scheme.  Generate is the ID generation module.  Serialize is the data serialization module.

       There are many modules included in this distribution.  For each role, they are:

	Store:
	   MySQL
	   Postgres
	   DB_File
	   File

	Lock:
	   Null
	   MySQL
	   Semaphore

	Generate:
	   MD5

	Serialize:
	   Storable
	   Base64
	   UUEncode

       In addition to the arguments needed by this module, you must provide whatever arguments are expected by the backing store and lock manager
       that you are using.  Please see the documentation for those modules.
