This blog has been updated to Nginx 1.5.10 with SPDY/3.1 + Google ngx_pagespeed enabled. You can read up on Centmin Mod’s Nginx + SPDY configuration here and test your own Nginx SPDY based SSL site using spdycheck.org online checking tool.
To visually see the differences between Nginx SPDY SSL vs non-SPDY SSL, I recreated the Apache mod_spdy World flags demo using Centmin Mod Nginx setup the video is at https://spdy.centminmod.com/spdytest.html and Nginx SPDY SSL World Flags demo is at https://spdy.centminmod.com/flags.html (site has also been updated to SPDY/3.1).
Browser extension tools to help detect SPDY:
- For Chrome browser, install SPDY Indicator extension.
- For Opera browser, install SPDY indicator extension.
- For Firefox browser, install SPDY indicator add-on.
- For Internet Explorer version 10 and below, the browser doesn’t support SPDY connections and will fall back to non-SPDY connections. Internet Explorer 11+ will support SPDY.
Akamai Technologies Youtube video explaining Google SPDY.
Apparently, Google has plans to remove the older SPDY/2 protocol support from Chrome 33 onwards, so Nginx folks get updating 🙂
