}

Proxy Handling

The actor employs a multi-tier proxy strategy to maximize successful data extraction.

1. Apify Residential Proxy (country-targeted) — First choice for Kyujin Box
2. Apify Residential Proxy (any region) — Fallback if country proxy unavailable
3. Apify Datacenter Proxy — Secondary fallback for cost efficiency
4. Direct Connection — Last resort when all proxies fail

Proxies auto-rotate on each request. Blocked sessions are discarded and replaced automatically.

Retry Logic

Failed requests are retried up to 5 times with automatic session rotation.

• Maximum 5 retries per request
• Fresh browser session on each retry
• Automatic proxy rotation between attempts
• Blocked status codes (401, 403, 429) trigger session refresh
• Configurable request timeout (120 seconds)

Anti-block Handling

The actor incorporates multiple stealth techniques to minimize detection.

• navigator.webdriver property masked
• Human-like delays between page interactions (2–5 seconds)
• Browser language and plugin fingerprints normalised
• Session pool with automatic rotation on blocks
• CAPTCHA detection with graceful retry
• Rate limit detection (HTTP 429) with backoff

Limitations

• Results depend on the portal's current HTML structure; layout changes may require selector updates
• Some job details (salary, benefits) may not be available for all listings
• Rate limiting by the portal may reduce throughput during high-volume scrapes
• CAPTCHA challenges may interrupt scraping on heavily protected pages
• Kyujin Box may modify their anti-bot measures, requiring periodic updates
• Maximum items per run is capped at 1000 to prevent excessive resource usage
• Proxy costs apply when using Apify residential or datacenter proxies
