Best Practice Behaviour of Body Handler

[Alex Chamberlain]

Hi all,

I've started to develop a RESTful interface onto MongoDB as an Nginx
Module. I've started to work on PUT requests, and I'm just wondering about
a couple of things with the body handler.

My content handler registers the body handler
using ngx_http_read_client_request_body.

When this gets called, if everything goes correctly, I either want to send
204 No Content or 303 See Other. Therefore, no body. What should I be
calling ngx_http_finalize_request with? I'm currently passing zero-length
buffers, and I'm getting alerts, so it must be wrong...

On the other hand, if something goes wrong, I suspect I should still be
calling ngx_http_finalize_request, right? If so, what should the arguements
be then?

Thanks for your help. My code can be found at
https://github.com/alexchamberlain/ngx-mongodb. I'd be very interested on
any feedback, but please bear in mind I'm relatively inexperienced, so I
expect to make mistakes and really won't mind any friendly advice.
