    Hi...

    I'm considering switching to http2, but not all of my hosting customers are on https yet and I also still have a few that have not updated their PHP version to 7.x. I just want to be sure that their websites will negotiate http1 with requesting browsers and that enabling http2 won't impact their site's performance in any way.

    Thanks!

    We've been using HTTP/2 with LiteSpeed for a long time now, and it hasn't caused any problems. If a site doesn't use SSL, it will serve the website over HTTP/1.1.

    I don't know how it works with Apache, but I'd guess it's similar.

    Hello,

    The previous post is correct. HTTP2 is only utilized when accessing the site using SSL (https://).

    Thank you.
