usage

Send any http request to the server, and it will respond with a json-formatted echo with all the things it knows about the request.

http https://echo.umputun.com/something

{
    "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip",
        "User-Agent": "HTTPie/2.4.0",
        "X-Forwarded-For": "12.12.12.12",
        "X-Forwarded-Host": "172.29.0.2:8080",
        "X-Origin-Host": "echo.umputun.com",
        "X-Real-Ip": "12.12.12.12"
    },
    "host": "172.29.0.2:8080",
    "message": "echo echo 123",
    "remote_addr": "172.29.0.3:37432",
    "request": "GET /something"
}

Alternatively, it can be run within cloudflare worker. In this case, the server will respond with the same echo. See cf-worker.js for details. The worker is available at https://echo.umputun.dev/.
