h1. Set up memcached

h2. Using a Foreman Plugin (1.2 and newer)

as of Foreman 1.2, there is now a plugin with auto configures memcache usage, see [[List_of_Plugins]]

h2. Manual configuration (1.1 and below)

As a Rails 3 application, foreman is fairly easy to connect to memcached. 

Instead of using memcache-client, we are going to use Dalli, a ruby gem that allows Rails to use your memcached store.

* Include <pre>gem 'dalli'</pre> on your Gemfile and run *bundle install*. 

* Open your environment config file, it is in config/environments/*.rb. Let's assume you will want to set memcached as your production cache store. (config/environments/production.rb)

* Add the following line in the Foreman::Aplication.configure block. <pre>config.cache_store = :dalli_store</pre> 

* Reboot your server (nginx, passenger, mongrel, thin..)

+Additional options+

If you have your own separate cache servers, just add it after the command like this: 

<pre>

config.cache_store = :dalli_store, 'cache1.myserver.com', 'cache2.myserver.com'

</pre>

 Memcached can be used to manage sessions, just add something like this to your config/initializers/session_store.rb:

<pre>

require 'action_dispatch/middleware/session/dalli_store'

Rails.application.config.session_store :dalli_store, :memcache_server => ['host1', 'host2'], :namespace => 'sessions', :key => '_foundation_session', :expire_after => 20.minutes

</pre>
