I agree with the last sentence. Happy Eyeballs is about the HTTP.
There are other applications protocols too. :-)
Happy eyeballs is about HTTP. But part of the approach predates "Happy
Eyeballs" -- please see RFC5461.
It's certainly true that we usually talk about Happy Eyeballs in the context
of HTTP, but I use it for ssh as well, and I think it's applicable across a
broad range of application protocols. It is not applicable to _every_
protocol, but that's as strong a qualification as I'd put on it—saying it's
only applicable to HTTP is not correct.
Exactly. For instance, I seem to recall benefiting of RFC5461 for ssh in
NetBSD long before the first version of the Happy Eyeballs I-D was
published.
As noted in RFC5461, the approach is useful for any protocol -- but for
obvious reasons the benefits become evident for interactive protocols
such as HTTP, SSH, telnet, and the like...
