> Issue Type: Bug
> Reporter: Jack Bates
>
> If there is a transform (for example a null transform) then the response
> headers aren't forwarded until the origin server starts sending content.
> Normally (without a transform) the headers are forwarded as soon as they are
> done, whether content is available yet or not.
> The headers are sent when the transform calls TSVConnWrite() and the
> transform is called at the end of the headers/start of the content. But it's
> not called if the available content is empty. A possible fix is to call the
> transform at the start of the content whether content is available yet or
> not. This doesn't affect a buffered transform which can still delay and
> update the headers until it calls TSVConnWrite()
