To me, it looks like you just return NGX_DONE and wait to be called
again when more data is available.

The problem is, on larger POST requests (~ > 2KB), ngx_http_read_client_request_body() sometimes returns NGX_AGAIN instead of NGX_OK. I have read at various places that if one receives any other status than NGX_OK that that the module should immediately return that status. I have also read that after getting and returning NGX_AGAIN, NGINX will call your module again after other pending network activity. However, I have tried doing this but my module never gets called again.
