Questions
Why does HTTP/2 matter?
It loads many files over one connection at the same time, which usually makes pages faster.
Does HTTP/2 need HTTPS?
In practice yes — all major browsers only use HTTP/2 over encrypted connections.
How do I turn it on?
Most modern servers and CDNs support it; it is often a single setting in your server or hosting panel.
