### Configuring URL Filtering

```java
// Include patterns (must match)
crawler.urlFilter.addInclude("https://example.com/.*");

// Exclude patterns (must not match)
crawler.urlFilter.addExclude(".*\\.(css|js|png|jpg)$");
```

### Setting Crawl Limits

```java
context.setMaxAccessCount(1000);  // Max URLs (0 = unlimited)
context.setMaxDepth(3);           // Max depth (-1 = unlimited)
