### 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

                        crawlerContext.intervalController.delay(IntervalController.NO_URL_IN_QUEUE);
                    }

                    threadCheckCount++;
                }

                // interval
                if (crawlerContext.intervalController != null) {
                    crawlerContext.intervalController.delay(IntervalController.WAIT_NEW_URL);
                }
            }

     * - Purges old crawling sessions
     * - Purges search logs older than configured days
     * - Purges job logs older than configured days
     * - Purges user info logs older than configured days
     * - Updates job log status
     *
     * @return a string containing the execution result and any error messages
