Spdy + http/2

Server NGINX
1

NGINX devs,

I know you were very excited to remove SPDY support from NGINX, but for
the
next few years there are a lot of devices (mobile devices that can’t
upgrade, end users who aren’t comfortable upgrading, etc) that are not
going to have http/2 support. By removing SPDY support you’ve created a
situation where we either have to penalize those users by forcing them
to
HTTP(S) connections, or we have to forego upgrading NGINX and not offer
HTTP/2.

Cloudflare is offering both SPDY and HTTP/2 - they are a huge NGINX shop
but I’m not clear if they are using NGINX to do that or not. I’d like to
encourage you to follow their lead and reinstate the SPDY support for a
while (even if its just a compile time option thats disabled by
default).

I think these “a lot” and “many years” are just overestimation based
on the marketing buzz around spdy, http2 and other so-called
innovations:

As you see, spdy penetration is just 6% and it starts to decline.
http/2 is still ~2% but growing super quickly.

And we do provide 1.8 branch which supports spdy.

Cloudflare is offering both SPDY and HTTP/2 - they are a huge NGINX
shop but I’m not clear if they are using NGINX to do that or not.

As for your request: can you explain how spdy deprecation affects you
personally (not Cloudflare or other).

Let me get back to you on that - we’re going to send some traffic
through
Cloudflare and see how the traffic breaks out given the choice of all
three
protocols.

Looks like Cloudflare patched SPDY support back into NGINX, and they
will
release the patch to everyone next year:

I was able to patch nginx-1.9.10 which supports both SPDY + HTTP2. I
don’t
intend to use both of them simultaneously on the same interface.

My question: Is there a reason why this is not done? It gives me an
option
to choose between the two per interface.

server {
listen x.x.x.x:443 ssl http2;
server_name abc.com;
…
}
server {
listen y.y.y.y:443 ssl spdy;
server_name def.com;
…
}

The answer is that there’s a huge difference between patching something
to get some feature for your own build and actually to provide support,
to keep maintaining the code.

We aren’t going to spend more time on maintaining already deprecated
experimental protocol. A lot of work is being done for every release
to find and fix bugs, to implement new features, to test on various
platforms. All these procedures are essentially to provide high quality
product for millions of users around the world with various use cases
and
configurations. Any additional line of code adds additional cost to
this
work.
