Perhaps there's an obvious answer to this question but it doesn't seem to be documented anywhere...

I have nginx running as a reverse proxy for a web application serving several large pages. Without nginx the page incrementally loads in the browser (streaming response) so the user is able to view it as it loads. Behind nginx the it hesitates and loads in one chunk. This indicates that nginx is reading the response from the backend and then serving it rather than streaming it to the client as it loads.

Is there anyway to get nginx to stream responses? To compare, Perlbal has this behavior implemented and the difference in the perceived speed when a large page loads is significant. If nginx can stream responses I assume it would be possible to turn off buffering to a file completely.

Thanks,
