사용자 정의 독점 헤더는 [`X-` 접두사를 사용](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)하여 추가할 수 있다는 점을 기억하세요.

하지만 브라우저에서 클라이언트가 볼 수 있게 하려는 사용자 정의 헤더가 있다면, [CORS (Cross-Origin Resource Sharing)](cors.md) 설정에 [Starlette의 CORS 문서](https://www.starlette.dev/middleware/#corsmiddleware)에 문서화된 `expose_headers` 매개변수를 사용해 추가해야 합니다.

# CORS（跨來源資源共用） { #cors-cross-origin-resource-sharing }

[CORS 或「Cross-Origin Resource Sharing」](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)指的是：當在瀏覽器中執行的前端以 JavaScript 與後端通訊，而後端與前端位於不同「來源（origin）」時的情境。

## 來源（Origin） { #origin }

一個來源是由通訊協定（`http`、`https`）、網域（`myapp.com`、`localhost`、`localhost.tiangolo.com`）與連接埠（`80`、`443`、`8080`）三者組合而成。

因此，以下皆是不同的來源：

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

/**
 * Interface representing a client for a web crawler.
 * This client is responsible for executing requests and handling responses.
 * It extends {@link AutoCloseable} to allow for resource management.
 */
public interface CrawlerClient extends AutoCloseable {

    /**
     * Sets the initialization parameters for the crawler client.
