 * **onConnect** `(abort: () => void, context: object) => void` - Invoked before request is dispatched on socket. May be invoked multiple times when a request is retried when the request at the head of the pipeline fails.
 * **onError** `(error: Error) => void` - Invoked when an error has occurred. May not throw.
 * **onUpgrade** `(statusCode: number, headers: Buffer[], socket: Duplex) => void` (optional) - Invoked when request is upgraded. Required if `DispatchOptions.upgrade` is defined or `DispatchOptions.method === 'CONNECT'`.
+* **onResponseStarted** `() => void` (optional) - Invoked when response is received, before headers have been read.
 * **onHeaders** `(statusCode: number, headers: Buffer[], resume: () => void, statusText: string) => boolean` - Invoked when statusCode and headers have been received. May be invoked multiple times due to 1xx informational headers. Not required for `upgrade` requests.
 * **onData** `(chunk: Buffer) => boolean` - Invoked when response payload data is received. Not required for `upgrade` requests.
 * **onComplete** `(trailers: Buffer[]) => void` - Invoked when response payload and trailers have been received and the request has completed. Not required for `upgrade` requests.
