This document describes nginx-module-zip v1.2.1 released on Jul 20 2022.
mod_zip assembles ZIP archives dynamically. It can stream component files from upstream servers with nginx's native proxying code, so that the process never takes up more than a few KB of RAM at a time, even while assembling archives that are (potentially) gigabytes in size.
mod_zip supports a number of "modern" ZIP features, including large files, UTC timestamps, and UTF-8 filenames. It allows clients to resume large downloads using the "Range" and "If-Range" headers, although these feature require the server to know the file checksums (CRC-32's) in advance. See "Usage" for details.
To unzip files on the fly, check out nginx-unzip-module.
Add a header "Content-Disposition: attachment; filename=foobar.zip" in the upstream response if you would like the client to name the file "foobar.zip"
To save bandwidth, add a "Last-Modified" header in the upstream response; mod_zip will then honor the "If-Range" header from clients.
To wipe the X-Archive-Files header from the response sent to the client, use the headers_more module: http://wiki.nginx.org/NginxHttpHeadersMoreModule
To improve performance, ensure the backends are not returning gzipped files. You can achieve this with
proxy_set_header Accept-Encoding "";in the location blocks for the component files.
