Is there any way reject WebSocket connection

[cwhan-yonsei]

Sometimes a WebSocket upgrade from a client needs to be rejected.
(e.g. upgrade request to wrong URI or client authentication)
However, it seems there is no way to reject the WebSocket upgrade request but to close the connection immediately.

  Is there any way to reject the upgrade?

Just don't call on_upgrade and return a different response.
