Tell me how to close a window and session via curl?

I found this solution, but it doesn't work:

curl -X DELETE http://127.0.0.1:4444/wd/hub/session/$s_id/window
curl -X DELETE http://127.0.0.1:4444/wd/hub/session/$s_id

And another question. Why doesn't the window close if the session is killed by SE_NODE_SESSION_TIMEOUT=300?
