      Throws:
      IOException - if unable to send the forbidden

      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.

    • setStatusCode

      void setStatusCode(int statusCode)

      a boolean indicating if the response has been committed.
