Upload progress system for Nginx
Upload progress module is an implementation of an upload progress system, that monitors RFC1867 POST uploads as they are transmitted to upstream servers. . It works by tracking the uploads proxied by Nginx to upstream servers without analysing the uploaded content and offers a web API to report upload progress in Javscript, Json or any other format.
