### Custom Interval Control

```java
// Configure politeness policy
container.singleton("intervalController", DefaultIntervalController.class, controller -> {
    controller.setDelayMillisForWaitingNewUrl(5000);
    controller.setDefaultIntervalTime(1000);
});
```

### Sitemap Support

```java
// Enable sitemap processing
container.singleton("sitemapsRule", SitemapsRule.class, rule -> {
