HTTP/2 (originally named HTTP/2.0) is the second major version of the HTTP network protocol used by the World Wide Web. HTTP/2 improves speed and provides better user experience.

Key Features

• Binary, instead of textual.
• Fully multiplexed, instead of ordered and blocking, can therefore use just one TCP connection.
• Uses header compression to reduce overhead.
• Allows servers to "push" responses proactively into client caches.

How to run an HTTP/2 and HTTPS server?

Generate a self-signed X.509 TLS certificate (HTTP/2 requires TLS to operate)

go run $GOROOT/src/crypto/tls/generate_cert.go --host localhost

This will generate cert.pem and key.pem files.

For demo purpose, we are using a self-signed certificate. Ideally you should obtain a certificate from CA.

Configure a server with engine.Config

server.go

{{< embed "http2/server.go" >}}

Endpoints

• https://localhost:1323/request (Displays the information about received HTTP request)
• https://localhost:1323/stream (Streams the current time every second)
