Supposed to help with navigation, I tried it before and it's not working for me like this, I go to http://www.dmm.com/netgame_s/kancolle/ with Cookie:ckcy=1; ... ckcy=2; and get redirected to /top/-/error/area/ with Set-Cookie:ckcy=2; expires=Thu, 04-Aug-2016 17:47:21 GMT; path=/; domain=dmm.com.

So http://www.dmm.com/netgame_s/kancolle/ (and http://www.dmm.com/netgame/social/application/-/detail/=/app_id=854854/) is "strict", while http://www.dmm.com/netgame/social/-/gadgets/=/app_id=854854/ isn't.
