## Problem

````text
Cloudflare Durable Object 가 hibernation API 로 놀고 있는 웹소켓을 많이 들고 있다. 클라이언트가 60초쯤마다 {"type":"ping"} 을 보내서, 핑마다 객체가 깨어나 실행 시간 요금이 늘었다.
````

## Solution

````text
Durable Object 생성자에서 ctx.setWebSocketAutoResponse(new WebSocketRequestResponsePair('{"type":"ping"}', '{"type":"pong"}')) 를 부른다. 글자가 정확히 같은 요청은 객체를 깨우지 않고 런타임이 바로 답한다. 소켓은 ctx.acceptWebSocket(server, [tag]) 로 받아 두면 나중에 ctx.getWebSockets(tag) 로 골라 보낼 수 있다.
