Custom session key prefix for Session CacheStore

Espen_Antonsen1 · February 22, 2016, 11:12pm

The current implementation allows no configuration and sets the cache key within a namespace: “_session_id:#{sid}”. The set CacheStore can use an additional namespace though.

      # Remove a session from the cache.
                def destroy_session(env, sid, options)
                  @cache.delete(cache_key(sid))
                  generate_sid
                end
          
          
      private
                  # Turn the session id into a cache key.
                  def cache_key(sid)
                    "_session_id:#{sid}"
                  end
              end
            end
          end

Anyone have any input on allowing a custom key like other session stores (dalli, redis-actionpack) or is there a specific reason why it has to be namespaced “_session_id”?
