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

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

응답은 다음과 같습니다:

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

## 요약

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

    return Multimaps.forMap(map).asMap();
  }

  @Override
  protected Map<String, Collection<Integer>> makePopulatedMap() {
    Map<String, Integer> map = new HashMap<>();
    map.put("foo", 1);
    map.put("bar", 2);
    map.put("cow", 3);
    return Multimaps.forMap(map).asMap();
  }

  @Override
  public void testEntrySetRemoveAllNullFromEmpty() {
    try {

          {
            set("foo");
          }
        };
    assertFalse(future.cancel(true));
    assertFalse(future.isCancelled());
    assertTrue(future.isDone());
  }

  public void testGetWithTimeoutDoneFuture() throws Exception {
    AbstractFuture<String> future =
        new AbstractFuture<String>() {
          {
            set("foo");
          }
        };

もし、その*path operation*で通信する場合は、次のように２つのHTTPヘッダーを送信します:

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

このレスポンスは以下のようになります:

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

## まとめ

ヘッダーは`Header`で宣言し、`Query`や`Path`、`Cookie`と同じパターンを使用する。

	fh := &FileHeader{

		ModifiedTime:     1234,
		ModifiedDate:     5678,

	testHeaderRoundTrip(fh, fh.UncompressedSize, uint64(fh.UncompressedSize), t)
}
