Overview

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 should need to be overwritten.

All parameters are optional.

  • :key determines the name of the cookie, by default it is ‘rack.session’

  • :domain and :path set the related cookie values, by default domain is nil, and the path is ‘/’.

  • :expire_after is the number of seconds in which the session cookie will expire. By default it is set not to provide any expiry time.
