Nginx: check content-length before file upload takes place

nginx

I'm trying to prevent users from uploading (accidentally or maliciously) very large files to my website.

I have nginx max_client_body_size set to 4M, but if a file larger than this is uploaded, then it uploads the entire file before returning 413 (entity too large).

I want to make nginx check the Content-Length header, so that it rejects the request before it's uploaded.

Alternatively, a Rails solution would also be acceptable.

Any help appreciated.
