#session ⇒ Object

Load the session information from the cookie. With the sessions plugin, you must call this method to get the session, instead of trying to access the session directly through the request environment. For maximum compatibility with other software that uses rack sessions, this method stores the session in ‘rack.session’ in the request environment, but that does not happen until this method is called.
