sendForbidden

public void sendForbidden(java.lang.String message)
                   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.

Specified by:

sendForbidden in interface UpgradeResponse

Parameters:

message - the short 1 line detail message about the forbidden response

Throws:

java.io.IOException - if unable to send the forbidden

setAcceptedSubProtocol

public void setAcceptedSubProtocol(java.lang.String protocol)

Set the accepted WebSocket Protocol.

Specified by:

setAcceptedSubProtocol in interface UpgradeResponse

Parameters:

protocol - the protocol to list as accepted

setExtensions

public void setExtensions(java.util.List<ExtensionConfig> extensions)

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.

Specified by:

setExtensions in interface UpgradeResponse

Parameters:

extensions - the list of extensions to use.

setHeader

public void setHeader(java.lang.String name,
                      java.lang.String value)

Specified by:

setStatusReason

public void setStatusReason(java.lang.String statusReason)

Specified by:

setStatusReason in interface UpgradeResponse

setSuccess

public void setSuccess(boolean success)

Specified by:

setSuccess in interface UpgradeResponse
