Das kann nützlich sein, wenn Sie beispielsweise in einem Land leben, in dem bestimmte URLs eingeschränkt sind.

### Die automatischen Dokumentationen deaktivieren

Der erste Schritt besteht darin, die automatischen Dokumentationen zu deaktivieren, da diese standardmäßig das Standard-CDN verwenden.

Um diese zu deaktivieren, setzen Sie deren URLs beim Erstellen Ihrer `FastAPI`-App auf `None`:

This could be useful if for example you live in a country that restricts some URLs.

### Disable the automatic docs { #disable-the-automatic-docs }

The first step is to disable the automatic docs, as by default, those use the default CDN.

To disable them, set their URLs to `None` when creating your `FastAPI` app:

{* ../../docs_src/custom_docs_ui/tutorial001.py hl[8] *}

   * href="https://url.spec.whatwg.org/#syntax-url-path-segment">URL path segments</a>. The returned
   * escaper escapes all non-ASCII characters, even though <a
   * href="https://url.spec.whatwg.org/#url-code-points">many of these are accepted in modern
   * URLs</a>. (<a href="https://url.spec.whatwg.org/#path-state">If the escaper were to leave these

```kotlin
cache.evictAll()
```

Removing individual items can be done using the urls iterator.
This would be typical after a user initiates a force refresh by a pull to refresh type action.

```java
    val urlIterator = cache.urls()
    while (urlIterator.hasNext()) {
      if (urlIterator.next().startsWith("https://www.google.com/")) {
        urlIterator.remove()
      }

     * Checks if a URL exists in the queue by searching OpenSearch and local caches.
     *
     * @param sessionId The session ID.
     * @param url The URL to check.
     * @return true if the URL exists in the queue, false otherwise.
     */
    @Override
    protected boolean exists(final String sessionId, final String url) {
        final boolean ret = super.exists(sessionId, url);
        if (!ret) {

     */
    @Size(max = 10000)
    public String virtualHostValue;

    /**
     * Enable or disable appending query parameters to search URLs.
     * When enabled, additional parameters are added to search result URLs.
     */
    @Size(max = 10)
    public String appendQueryParameter;

    /**
     * Enable or disable login requirement for search access.

   * href="https://url.spec.whatwg.org/#syntax-url-path-segment">URL path segments</a>. The returned
   * escaper escapes all non-ASCII characters, even though <a
   * href="https://url.spec.whatwg.org/#url-code-points">many of these are accepted in modern
   * URLs</a>. (<a href="https://url.spec.whatwg.org/#path-state">If the escaper were to leave these

    }

    /**
     * Retrieves a list of URLs that should be excluded from crawling based on failure counts.
     * URLs are excluded if they have failed more than the configured failure count threshold.
     * URLs can also be filtered by failure type using a regular expression pattern.
     *
     * @param configId the configuration ID to get excluded URLs for

Esto podría ser útil si, por ejemplo, vives en un país que restringe algunas URLs.

### Desactiva la documentación automática

El primer paso es desactivar la documentación automática, ya que por defecto, esos usan el CDN predeterminado.

Para desactivarlos, establece sus URLs en `None` cuando crees tu aplicación de `FastAPI`:

{* ../../docs_src/custom_docs_ui/tutorial001.py hl[8] *}

        final Map<String, Object> requestBody = new HashMap<>();
        final String urls = "https://www.codelibs.org/" + "\n" + "http://failure.url";
        final String includedUrls = "https://www.codelibs.org/.*" + "\n" + "http://failure.url.*";
        requestBody.put("name", NAME_PREFIX + "WebConfig");
        requestBody.put("urls", urls);
        requestBody.put("included_urls", includedUrls);
