Announcing NGINX Plus R8


We are proud to announce the availability of NGINX Plus Release 8 (R8), the latest release of our application delivery platform. This release includes a fully production‑ready and hardened implementation of HTTP/2, a persistent on‑the‑fly reconfiguration API, the new Slice module for scalable caching of large video files, and many more features to ensure flawless application delivery.

Editor – NGINX Plus R8 also introduced the OAuth Technology Preview. For information about it, see below.

NGINX Plus R8 Features in Detail

This section provides a detailed overview of all the new features and functionality in NGINX Plus R8.

OAuth Technology Preview

Editor – In NGINX Plus R8 we introduced the OAuth Technology Preview, an implementation of authentication using the OAuth 2.0 standard, and details originally appeared here. In NGINX Plus R10, we replaced the OAuth Technology Preview with native support for the JSON Web Token (JWT) standard.

Production-Ready HTTP/2 Implementation

HTTP/2 is the latest version of the HTTP protocol. It fixes a lot of the problems in the original version of the HTTP protocol, leading to better overall performance and more efficient resource utilization.

The usage of HTTP/2 has been steadily increasing since the standard was ratified in February 2015. As of this writing, 6% of all websites use HTTP/2 and 69% of users on the Internet use a browser that supports HTTP/2.

With NGINX Plus R8, you are getting the most battle‑tested, stable, and reliable implementation of HTTP/2 available today. 71% of HTTP/2‑enabled websites are powered by NGINX and NGINX Plus, and we’ve incorporated feedback from our early adopters into the product. Our HTTP/2 implementation is fully supported for production use and can scale to handle the toughest workloads.

NGINX acts a "gateway" between clients that use HTTP/2 and upstream servers, with which it uses HTTP/1.x, FastCGI, or other unsecured protocols
NGINX Plus acts as an HTTP/2 Gateway

NGINX Plus acts as an “HTTP/2 gateway” to ease transition to the new protocol. On the frontend, NGINX Plus talks HTTP/2 to client web browsers that support it. On the backend, NGINX Plus talks HTTP/1.x (or FastCGI, SCGI, uwsgi, etc.), just as before. In between, NGINX Plus translates between HTTP/2 and HTTP/1.x (or FastCGI, etc). This means that servers and applications proxied by NGINX Plus are unaffected by the move to HTTP/2, and don’t really even need to know whether their clients are using HTTP/2. Websites and applications that service HTTP/2 clients must use TLS/SSL, however, as required by all web browsers that support HTTP/2.

The only NGINX Plus or NGINX configuration change you need to make is adding the http2 parameter to listen directives:

listen 443 ssl http2 default_server;

For more details on HTTP/2 in NGINX Plus and NGINX, please see our white paper and on‑demand webinar.

Persistent On-the-Fly Reconfiguration

NGINX Plus provides an HTTP‑based API for adding, removing, and modifying backend servers dynamically and without having to reload the configuration. This is a great feature for service discovery, autoscaling, and other applications that require adding and removing servers on demand.

With NGINX Plus R8, changes made using this API can now be persistent across NGINX Plus restarts and configuration reloads. Add the new state directive in an upstream block to name the file in which NGINX Plus stores state information for the servers in the upstream group. Changes that you make with the on‑the‑fly reconfiguration API are recorded in the file. NGINX Plus reads the file at startup, which is how your changes persist across restarts.

upstream backend {
    zone backend 64k;
    state /var/lib/nginx/state/backend.state;

The state directive names the file in which NGINX Plus stores state information for the servers in the upstream group. When it is included in the configuration, servers cannot be statically defined using the server directive.

The user nginx must have write permission on the /var/lib/nginx/state/ directory. If the directory does not already exist, you can run these commands:

$ sudo mkdir -p /var/lib/nginx/state
$ sudo chown nginx:nginx /var/lib/nginx/state

Scalable Caching for Large Video Files

Caching is one of the quickest ways to accelerate delivery of web content. Not only does caching place content closer to the end user, reducing latency, it also reduces the number of requests to the upstream origin server, lowering bandwidth usage and effectively increasing capacity. Video, especially HTML5 video, is a prime target for caching, because the content is static and tends to be heavily requested when first published.

With HTML5 video, the browser pseudostreams content by making HTTP byte‑range requests. It requests the first minute of video, for example, and then the second minute, and so on. Streaming in this way also makes it easy to implement fast‑forward and rewind functionality, as the browser can just skip over sections of video it doesn’t need, instead beginning the requested byte range at the point the user fast‑forwarded or rewinded to.

NGINX Plus R8 includes the new Slice module to better support this style of browser‑server interaction for cached video files. The module breaks up files into smaller fragments and then caches those fragments. Structuring the cache in this way better aligns with modern video streaming techniques, such as those used by HTML5 video.

To enable cache slicing, include the slice directive:

proxy_cache_path /tmp/mycache keys_zone=mycache:10m;

location / {
    proxy_cache  mycache;
    proxy_pass   http://localhost:8000;

    slice              1m;
    proxy_cache_key    $uri$is_args$args$slice_range;
    proxy_set_header   Range $slice_range;
    proxy_http_version 1.1;
    proxy_cache_valid  200 206 1h;

In this sample configuration, NGINX Plus breaks video files into 1 MB fragments. You must also include the following directives:
