Wenn Sie jedoch benutzerdefinierte Header haben, die ein Client in einem Browser sehen können soll, müssen Sie diese zu Ihrer CORS-Konfiguration hinzufügen (weitere Informationen finden Sie unter [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md)), unter Verwendung des Parameters `expose_headers`, dokumentiert in [Starlettes CORS-Dokumentation](https://www.starlette.dev/middleware/#corsmiddleware)....

But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations (read more in [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md)), using the parameter `expose_headers` documented in [Starlette's CORS docs](https://www.starlette.dev/middleware/#corsmiddleware)....

# CORS (Cross-Origin Resource Sharing) { #cors-cross-origin-resource-sharing }

[CORS oder <abbr title="Ressourcenfreigabe zwischen Ursprüngen">„Cross-Origin Resource Sharing“</abbr>](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) bezieht sich auf Situationen, in denen ein Frontend, das in einem Browser läuft, JavaScript-Code enthält, der mit einem Backend kommuniziert, und das Backend sich in einem anderen „Origin“ als das Frontend befindet.

## Origin { #origin }

      tags:
        - key: name
          value: pick* # match objects with tag 'name', all values starting with 'pick'
      metadata:
        - key: content-type
          value: image/* # match objects with 'content-type', all values starting with 'image/'
      size:
        lessThan: "10MiB" # match objects with size less than this value (e.g. 10MiB)

This program downloads a URL and prints its contents as a string. [Full source][get_example].

```java
OkHttpClient client = new OkHttpClient();

String run(String url) throws IOException {
  Request request = new Request.Builder()
      .url(url)
      .build();

  try (Response response = client.newCall(request).execute()) {
    return response.body().string();
  }
