Overview

Port of Action Controller’s cookie-based session store (Copyright © 2004-2008 David Heinemeier Hansson).

Rack::Session::HashedCookie provides simple cookie based session management. The session is a Ruby Hash stored as base64 encoded marshalled data set to :key (default: rack.session).

Example:

use Rack::Session::Cookie, :key => 'rack.session',
                           :domain => 'foo.com',
                           :path => '/',
                           :expire_after => 2592000,
                           :digest => 'SHA256',
                           :secret => 'my long secret string'

All parameters but :secret are optional.
