## Pruning the Cache

Pruning the entire Cache to clear space temporarily can be done using evictAll.

```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()) {

O `@app.get("/")` diz ao **FastAPI** que a função logo abaixo é responsável por tratar as requisições que vão para:

* a rota `/`
* usando o  <abbr title="o método HTTP GET">operador <code>get</code></abbr>

!!! info "`@decorador`"
    Essa sintaxe `@alguma_coisa` em Python é chamada de "decorador".

    Você o coloca em cima de uma função. Como um chapéu decorativo (acho que é daí que vem o termo).
