## Examples

### Web Crawling with Custom Rules

```java
// Create crawler with custom configuration
StandardCrawlerContainer container = new StandardCrawlerContainer();

// Configure HTTP client with custom settings
container.singleton("httpClient", HcHttpClient.class, client -> {
    client.setUserAgent("MyBot/1.0");
