Und **Ihre Benutzer** definieren auf irgendeine Weise (zum Beispiel irgendwo in einem Web-Dashboard) die **URL**, an die Ihre Anwendung diese Requests senden soll.

Die gesamte **Logik** zur Registrierung der URLs für Webhooks und der Code zum tatsächlichen Senden dieser Requests liegt bei Ihnen. Sie schreiben es so, wie Sie möchten, in **Ihrem eigenen Code**.

     * is {@code a -> b -> c}. This method handles well the case for transitive list. But, for non-transitive we need
     * to "pull in" transitive dependencies of eliminated projects, as for case above, the properly filtered list would
     * be {@code a -> c}.
     * <p>

```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()
      }

  - 새로운 **기능**을 제안 합니다.

  ## Pull Request를 만드십시오

  Pull Requests를 이용하여 소스코드에 [컨트리뷰트](https://github.com/fastapi/fastapi/blob/master/docs/en/docs/contributing.md){.internal-link target=_blank} 할 수 있습니다. 예를 들면 다음과 같습니다:

  - 문서에서 찾은 오타를 수정할 때.

 *  **There is no longer a global singleton connection pool.** In OkHttp 2.x,
    all `OkHttpClient` instances shared a common connection pool by default.
    In OkHttp 3.x, each new `OkHttpClient` gets its own private connection pool.
    Applications should avoid creating many connection pools as doing so
    prevents connection reuse. Each connection pool holds its own set of

Pode ser muito útil para configurar **recursos** que você precisa usar por toda aplicação, e que são **compartilhados** entre as requisições, e/ou que você precisa **limpar** depois. Por exemplo, o pool de uma conexão com o banco de dados ou carregamento de um modelo compartilhado de aprendizado de máquina (_machine learning_).

## Caso de uso

Vamos iniciar com um exemplo de **caso de uso** e então ver como resolvê-lo com isso.

Da wir zum Beispiel im `Image`-Modell ein Feld `url` haben, können wir deklarieren, dass das eine Instanz von Pydantics `HttpUrl` sein soll, anstelle eines `str`:
