A straightforward use of a series of request.write()s with a request.finish() in the render_GET() method of a resource defaults to chunked encoding.  I can avoid the chunked encoding by computing the entire response first using a StringIO (as shown below) and explicitly putting the &quot;Content-Length&quot; header in myself.<div>
