Rack::Session::File

Rack session store on plain file system.

Usage in Rack Applications

On Gemfile:

gem 'rack-session-file'

And use Rack::Session::File as Rack Middleware:

use Rack::Session::File, :storage => ENV['TEMP'],
                         :expire_after => 1800

NOTICE: Never use this module in conjunction with other session middlewares (especially Rack::Session::Cookie). That would brake session handling.

For Sinatra and Padrino

Do not enable session mechanism by enable :session. Built-in session of Sinatra (and Padrino) utilizes Rack::Session::Cookie, so it will interfere this module's behavior. Using this middleware makes session[] available in your application without enable :session.

Usage in Rails 3 Applications

On Gemfile:

gem 'rack-session-file', :require => 'rails-session-file'

And modify your config/initializers/session_store.rb to something like:

FooBar::Application.config.session_store :file_store,
  :key => '_foobar_session', :driver => 'YAML'

Options

File storage directory (:storage)

Default is Dir.tmpdir.

Backend serializer (:driver)

You can specify backend serializer via :driver option.

use Rack::Session::File, :driver => :YAML

Bundled drivers are:

• :PStore (default)
• :YAML
• :Marshal (discouraged to use)

Also you can use backend driver class explicitly.

use Rack::Session::File::YAML
