When a browser is making a CORS request, it may sometimes first send an OPTIONS request, to check whether the server understands the CORS protocol. This is optional, and doesn't happen for every request or in every browser. If an OPTIONS request does get sent, and is not then handled by the server, the browser will fail the underlying request. The proper way to handle this is to send a 204 response ("no content") with the CORS headers attached. (These headers are automatically added to every outgoing response, including OPTIONS responses, via set_default_headers().)
