### CrawlerThread (`CrawlerThread.java`)

Worker thread for crawling.

**Flow**: Poll URL → Validate → Get client → Delay → Check last-modified → Execute → Process → Extract children → Queue children → Delay

### CrawlerClientFactory

Pattern-based client selection using `LinkedHashMap<Pattern, CrawlerClient>`.

**Standard Patterns**:
```java

import (
	"context"
	"errors"
)

// errMaxVersionsExceeded return error beyond 10000 (default) versions per object
var errMaxVersionsExceeded = StorageErr("maximum versions exceeded, please delete few versions to proceed")

// errUnexpected - unexpected error, requires manual intervention.
var errUnexpected = StorageErr("unexpected error, please report this issue at https://github.com/minio/minio/issues")

    val realChain = chain as RealInterceptorChain
    val exchange = realChain.call.initExchange(realChain)
    val connectedChain = realChain.copy(exchange = exchange)
    return connectedChain.proceed(realChain.request)
  }
