## Language Detection and Selection

### User Interface Language

Fess determines the UI language in this order:

1. **Query parameter**: `?browser_lang=[locale]` (highest priority)
2. **Browser header**: `Accept-Language` header
3. **Fallback**: English (from `fess_label.properties` and `fess_message.properties`)

### Document Language Detection

During crawling and indexing, Fess:

it is randomized which cluster might provision the bucket.

### 3. Test your setup

To test this setup, access the MinIO server via browser or [`mc`](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart). You’ll see the uploaded files are accessible from the all the MinIO endpoints.

dass benutzerdefinierte proprietäre Header hinzugefügt werden können [unter Verwendung des `X-`-Präfixes](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

Wenn Sie jedoch benutzerdefinierte Header haben, die ein Client in einem Browser sehen soll, müssen Sie sie zu Ihrer CORS-Konfiguration ([CORS (Cross-Origin Resource Sharing)](cors.md)) hinzufügen, indem Sie den Parameter `expose_headers` verwenden, der in [Starlettes CORS-Dokumentation](https://www.starlette.dev/middleware/#corsmiddleware)...

Caching
=======

OkHttp implements an optional, off by default, Cache. OkHttp aims for RFC correct and
pragmatic caching behaviour, following common real-world browser like Firefox/Chrome and
server behaviour when ambiguous.

# Basic Usage

```kotlin
  private val client: OkHttpClient = OkHttpClient.Builder()
      .cache(Cache(
          directory = File(application.cacheDir, "http_cache"),
          // $0.05 worth of phone storage in 2020

#   System.out.println(pkg + "**");
# }
#
@defaultMessage non-public internal runtime class

com.sun.activation.registries.**
com.sun.browser.**
com.sun.corba.se.**

    assertFalse(Ascii.equalsIgnoreCase("[", "{"));
  }

  @GwtIncompatible // String.toUpperCase() has browser semantics
  public void testEqualsIgnoreCaseUnicodeEquivalence() {

    assertFalse(Ascii.equalsIgnoreCase("@", "`"));
    assertFalse(Ascii.equalsIgnoreCase("[", "{"));
  }

  @GwtIncompatible // String.toUpperCase() has browser semantics
  public void testEqualsIgnoreCaseUnicodeEquivalence() {
    // Note that it's possible in future that the JDK's idea to toUpperCase() or equalsIgnoreCase()

        if (!ignoredArtifacts.contains(artifact)) {
            logger.warn("\n\tArtifact " + artifact + " retains local artifactScope '" + artifact.getScope()
                    + "' overriding broader artifactScope '" + ignoredScope + "'\n"
                    + "\tgiven by a dependency. If this is not intended, modify or remove the local artifactScope.\n");
            ignoredArtifacts.add(artifact);
        }
    }

因此，前端（在瀏覽器中執行）會嘗試存取 `/openapi.json`，但無法取得 OpenAPI 模式。

因為我們的應用前面有一個將路徑前綴設定為 `/api/v1` 的代理，所以前端需要從 `/api/v1/openapi.json` 取得 OpenAPI 模式。
