SPDYcheck.org gives the thumbs up all round, with its only criticism being

Out-of-Date SPDY Protocol Support
The most recent version of SPDY is spdy/3. The highest version this website 
supports is spdy/2. There are 3 major versions of SPDY. This website should 
consider updating its software if possible to support spdy/3.

(Nginx 1.5.6, openSSL 1.0.1e - both latest versions I think, how could I get spdy/3 if I wanted it?)

But when I check it in my browser, through

chrome://net-internals/#events&q=type:SPDY_SESSION%20is:active

it doesn't show up. Other sites like google et al DO.

I also installed a chrome extension that puts a green lightning bolt in the address bar if SPDY is detected. Google = green bolt. My site = no green bolt.

I tried https://isspdyenabled.com/ to double-test my browser, and it told me that

This connection uses SPDY_VERSION: 3

So is the problem that my browser is refusing to use spdy/2 when it wants to use spdy/3 instead?

Or am I maybe using some cipher suite that is incompatible with SPDY, if that's even possible?

According to the documentation, nginx only supports SPDY/2.

Why your site does not show as SPDY enabled, you gave too little information (no config files, etc.).

If you want a server that supports SPDY/3 you can look into Jetty (documentation), which also does SPDY Push with these results.

Apache HTTPD also supports SPDY/3 via mod_spdy, but to my knowledge does not do SPDY Push automatically like Jetty does.

  • I was hoping for a pointer as to what tools/methods I should use to debug this and get to the bottom of it. But I think it was just down to me using an alpha version of Chrome. – Codemonkey Oct 10 '13 at 23:06
  • @Codemonkey You should have clearly mentioned what you are hoping for in the question to answer it accordingly. – Pothi Kalimuthu Oct 11 '13 at 01:32

I think this is a bug in my canary release of Chrome. On my laptop on a stable release it works fine.
