require a fair amount of overhead and added latency. OkHttp will make every effort to reuse existing connections to avoid this overhead and added latency.

Every OkHttpClient uses a connection pool. Its job is to maintain a reference to all open connections. When an HTTP request is started, OkHttp will attempt to reuse an existing connection from the pool. If there are no existing connections, a new one is created and put into the connection pool. For HTTP/2, the connection can be reused immediately....

   * <p>For example, if {@code rangeMap} had the entries {@code [1, 5] => "foo", (6, 8) => "bar",
   * (10, ∞) => "baz"} then {@code rangeMap.subRangeMap(Range.open(3, 12))} would return a range map
   * with the entries {@code (3, 5] => "foo", (6, 8) => "bar", (10, 12) => "baz"}.
   *
   * <p>The returned range map supports all optional operations that this range map supports, except

// with control characters, this is a specialized extension
// to support AWS S3 compatible behavior.

// Do not use this function for anything other than ListObjects()
// variants, please open a github discussion if you wish to use
// this in other places.

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

내부적으로 `open("./somefile.txt")` 는 "컨텍스트 관리자(Context Manager)"라고 불리는 객체를 생성합니다.

`with` 블록이 끝나면, 예외가 발생했더라도 파일을 닫도록 보장합니다.

5. Ensure all tests pass: `mvn test`
6. Check license headers: `mvn license:format`
7. Commit changes: `git commit -m 'Add amazing feature'`
8. Push to branch: `git push origin feature/amazing-feature`
9. Open a Pull Request

### Code Style

- Use Eclipse formatter configuration (`src/config/eclipse/formatter/java.xml`)
- Follow existing naming conventions
- Add comprehensive JavaDoc for public APIs
