Якщо ви взаємодієте з цією *операцією шляху*, надсилаючи два HTTP-заголовки, наприклад:

```
X-Token: foo
X-Token: bar
```

Відповідь буде така:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

다음과 같은 두 개의 HTTP 헤더를 전송하여 해당 *경로 처리* 와 통신할 경우:

```
X-Token: foo
X-Token: bar
```

응답은 다음과 같습니다:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

`Header`는 `Query`, `Path`, `Cookie`와 동일한 패턴을 사용하여 선언합니다.

### 결과 응답 { #the-resulting-response }

클라이언트가 `http://example.com/items/foo`( `item_id` `"foo"`)를 요청하면, HTTP 상태 코드 200과 다음 JSON 응답을 받습니다:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

하지만 클라이언트가 `http://example.com/items/bar`(존재하지 않는 `item_id` `"bar"`)를 요청하면, HTTP 상태 코드 404("not found" 오류)와 다음 JSON 응답을 받습니다:

```JSON
