When using publisher, it's sufficient to simply return a string. The 
Content-Type is set automatically to text/html if the string looks like 
HTML, text/plain if it doesn't. I've never found the need for 
req.write() with publisher, but I suppose it could be used to avoid 
consuming too much memory when building very large pages.
