Response Headers

// set header based on filename - will force a Save As from the browse if it doesn't recognize it
// this is better than the default response of the browser trying to display the contents
res.setHeader("Content-Disposition", headerValue);


// set mimetype for the content and the character encoding + length for the stream
res.setContentType(mimetype);
res.setContentEncoding(reader.getEncoding());
res.setHeader("Content-Length", Long.toString(reader.getSize()));
