NGX_AGAIN and POST data

I believe I have solved my problem. At the end of my request body
post_handler, I am now doing this:
rc = ngx_http_output_filter(r, &out);
I still not sure this is quite right, particularly on which value I
should be sending for the second argument to
ngx_http_finalize_request(), but it does seem to work reliably.
Thank you for all your help,
