ID sets up a basic framework for implementing an id based sessioning service. Cookies sent to the client for maintaining sessions will only contain an id reference. Only get_session and set_session are required to be overwritten.

All parameters are optional.

• :key determines the name of the cookie, by default it is ‘rack.session‘
• :path, :domain, :expire_after, :secure, and :httponly set the related cookie options as by Rack::Response#add_cookie
• :skip will not a set a cookie in the response nor update the session state
• :defer will not set a cookie in the response but still update the session state if it is used with a backend
• :renew (implementation dependent) will prompt the generation of a new session id, and migration of data to be referenced at the new id. If :defer is set, it will be overridden and the cookie will be set.
• :sidbits sets the number of bits in length that a generated session id will be.

These options can be set on a per request basis, at the location of env. Additionally the id of the session can be found within the options hash at the key :id. It is highly not recommended to change its value.

Is Rack::Utils::Context compatible.

Not included by default; you must require ‘rack/session/abstract/id’ to use.
