The output buffer has already been flushed either manually by calling response.flushBuffer() or because you've written more to the response than the buffer size.

This commits the response and causes the status code and headers to be sent to the client.

Because you've sent the headers you can't then perform a redirect because that is sent as an HTTP header.
