HTTP/2 Two Years Later
summary
HTTP/2 adoption details, Java support and deployment lessons: Jetty adds HTTP/2 and ALPN support in Jetty 9.4 with ALPN support and recommends JDK8+/JDK9 builds; servlet API will expose programmatic push. Best deploy end-to-end HTTP/2 (avoid Apache/nginx proxying HTTP/1.1); use HAProxy TLS tunnel to backend or terminate TLS at app to enable server push. Measured effects include a lab simulated 100ms RTT showed ~60% render time reduction with HTTP/2 push; browser implementations vary (Chrome ~600ms, Firefox >1s, Edge ~1.7s) and packet loss affects ~20% of connections.
