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()) {
      if (urlIterator.next().startsWith("https://www.google.com/")) {
        urlIterator.remove()

   ```

2. **Access the Admin UI:**
   ```
   http://localhost:8080/admin/
   ```

3. **Test language selection:**
   - Check if your language appears in the language dropdown
   - Force your language by adding URL parameter: `?browser_lang=[locale]`
   - Example: `http://localhost:8080/admin/?browser_lang=sv`

4. **Verify translations:**
   - Navigate through different admin pages
