At its core, Caddy's configuration is simply a JSON document.

• caddy.json

{
	"apps": {
		"http": {
			"servers": {
				"example": {
					"listen": [":2015"],
					"routes": [
						{
							"handle": [{
								"handler": "static_response",
								"body": "Hello, world!"
							}]
						}
					]
				}
			}
		}
	}
}

• test

$ curl localhost:2019/load \
        -H "Content-Type: application/json" \
        -d @caddy.json
$ curl localhost:2019/config/
{"apps":{"http":{"servers":{"example":{"listen":[":2015"],"routes":[{"handle":[{"body":"Hello, world!","handler":"static_response"}]}]}}}}}

$ curl localhost:2015
Hello, world!
