⇱ A 200 response is not proof that a proxy setup works - DEV Community


A residential proxy setup can look “fine” in testing and still fail in production.

A 200 response does not tell you:

  • whether the page is challenged
  • whether the geo is correct
  • whether retries are already too expensive
  • whether the session survives long enough for real workflows

For scraping, I think “cost per successful usable page” is often a better metric than cost per GB.

What are you measuring first when validating a proxy pool?
