title: Is it possible that a reverse proxy upgrades a http/1.1 connection to http2?
body: <p>Not really sure whether is possible or not, but if you have a reverse proxy for HTTP/1.1 connections, would it be possible to ugprade from the reverse proxy, said connections to HTTP/2, if the destination is capable of serving HTTP/2? </p>
  
  <p>If it helps, the proxy is written in go, and it makes use of the <a href="https://golang.org/pkg/net/http/httputil/#ReverseProxy" rel="nofollow noreferrer">reverseproxy</a> package.</p>
