// WebSocketHandshakeThrottle provides a facility for embedders to delay
// WebSocket connection establishment. Specifically, at the same time as the
// handshake is started blink::Platform::CreateWebSocketHandshakeThrottle() will
// be called. If a non-null WebSocketHandshakeThrottle is returned then
// ThrottleHandshake() will be called on it. If the result is error then the
// handshake will be aborted, and a connection error will be reported to
// Javascript. If the throttle hasn't reported a result when the WebSocket
// handshake succeeds then Blink will wait for the throttle result before
// reporting the connection is open to Javascript.
