I'm very new to concept HTTP/1.1 or HTTP/2, I'm wondering from a web developer perspective, do any of these has to do with us? Do we have to refactor our code in order to utilize HTTP/2? Or most of these has to do with the browser instead?
I understand that this may looks like a off-topic as too broad question, I've also done my own studies however unable to understand it from a web developer's point of view. Wondering if anyone can help shed some light?
