        if (content == null) {
            writer.flush();
            writer.close();
            final int length = sosi.getOutputStream().toByteArray().length;
            setHeader("Content-Length", length + "");
        } else {
            setHeader("Content-Length", content.getContentLength() + "");
        }
    }
{code}
