HTTP2 behind NGINX cache/reverse proxy

[naanlizard]

I've got OME set up with a simple origin and edge combined instance behind an nginx reverse proxy subdomain

I've been taking a closer look at logging/etc lately and found that I'm getting HTTP1.1 requests for llhls chunks with my current config.

Here's my Server.xml for reference. The big question here is, do I need

        <HTTP2>
            <Enable>true</Enable>
        </HTTP2>

somewhere, as the docs suggest?

Or is it enabled by default, like LLHLS must be ?

I understand it's only available on the TLS port, correct?

Does any of this even matter? e.g. if the nginx->OME connection is http and only http 1.1, is that going to be noticeable compared to http2?

An HTTP server will only know if a client wants to connect over http/2 if it uses TLS. There will be no noticeable performance improvement between servers, since clients will be using multiple connections on top of http1.1 anyway.
