                    throws java.io.IOException
        Issue a forbidden upgrade response.

        This means that the websocket endpoint was valid, but the conditions to use a WebSocket resulted in a forbidden access.

        Use this when the origin or authentication is invalid.

        Parameters:
        message - the short 1 line detail message about the forbidden response
        Throws:
        java.io.IOException - if unable to send the forbidden

        Set the list of extensions that are approved for use with this websocket.

        Notes:

        • Per the spec you cannot add extensions that have not been seen in the UpgradeRequest, just remove entries you don't want to use
        • If this is unused, or a null is passed, then the list negotiation will follow default behavior and use the complete list of extensions that are available in this WebSocket server implementation.
        Parameters:
        extensions - the list of extensions to use.
