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:

Throws:

IOException

setAcceptedSubProtocol

setExtensions

public void setExtensions(List<ExtensionConfig> extensions)

Description copied from interface: UpgradeResponse

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

This is Advanced usage of the WebSocketCreator to allow for a custom set of negotiated extensions.

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.

Specified by:

setExtensions in interface UpgradeResponse

Parameters:

extensions - the list of extensions to use.

setHeader

public void setHeader(String name,
             String value)
