provides simple cookie based session management. By default, the session is a Ruby Hash stored as base64 encoded marshalled data set to :key (default: rack.session). The object that encodes the session data is configurable and must respond to <tt>encode</tt> and <tt>decode</tt>. Both methods must take a string and return a string.</p> <p>When the secret key is set, cookie data is checked for data integrity. The old secret key is also accepted and allows graceful secret rotation.</p> <p>Example:</p> <pre>use Rack::Session::Cookie, :key => 'rack.session', :domain => 'foo.com', :path => '/', :expire_after => 2592000, :secret => 'change_me', :old_secret => 'also_change_me' All parameters are optional.</pre> <p>Example of a cookie with no encoding:</p> <pre>Rack::Session::Cookie.new(application, { :coder => Rack::Session::Cookie::Identity.new })</pre> <p>Example of a cookie with custom encoding:</p> <pre>Rack::Session::Cookie.new(application, { :coder => Class.new { def encode(str); str.reverse; end def decode(str); str.reverse; end }.new })</pre> </div><!-- description --> <div id="5Buntitled-5D" class="documentation-section"> <!-- Attributes --> <div id="attribute-method-details" class="method-section section"> <h3 class="section-header">Attributes</h3> <div id="coder-attribute-method" class="method-detail"> <a name="coder"></a> <div class="method-heading attribute-method-heading"> <span class="method-name">coder</span><span class="attribute-access-type">[R]</span> </div> <div class="method-description"> </div> </div> </div><!-- attribute-method-details --> <!-- Methods --> <div id="public-class-method-details" class="method-section section"> <h3 class="section-header">Public Class Methods</h3> <div id="new-method" class="method-detail "> <a name="method-c-new"></a> <div class="method-heading"> <span class="method-name">new</span><span class="method-args">(app, options={})</span> <span class="method-click-advice">click to toggle source</span> </div> <div class="method-description"> <div class="method-source-code" id="new-source"> <pre> <span class="ruby-comment"># File lib/rack/session/cookie.rb, line 105</span> <span class="ruby-keyword">def</span> <span class="ruby-identifier">initialize</span>(<span class="ruby-identifier">app</span>, <span class="ruby-identifier">options</span>={}) <span class="ruby-ivar">@secrets</span> = <span class="ruby-identifier">options</span>.<span class="ruby-identifier">values_at</span>(<span class="ruby-value">:secret</span>, <span class="ruby-value">:old_secret</span>).<span class="ruby-identifier">compact</span> <span class="ruby-identifier">warn</span> <span class="ruby-string"> SECURITY WARNING: No secret option provided to Rack::Session::Cookie.
