Designing Resilient Proxy Rotation for a Scraper

A reliable scraper is not just fast, but also knows how to stop, retry, and switch routes politely.

Key Points

• Respect robots.txt and site terms, and limit the request rate so the target server is not overloaded.
• Use a healthy proxy pool and remove proxies that repeatedly fail from the rotation.
• Apply retries with increasing delays (exponential backoff) and a maximum attempt limit.
• Log every failure with its cause so problem patterns are easy to spot.

Collect only data you are allowed to collect, and store it securely.
