A redirect chain is a sequence of HTTP redirects a request follows before reaching its final destination URL. Each redirect points to another URL instead of returning the requested content directly.
A client requests a URL, and the server responds with a 3xx status code along with a new location header instead of the page content. The client follows that new URL, which might trigger another redirect, and this can repeat several times. Each hop in the chain adds a small delay, and most browsers and scraping tools cap the number of redirects they will follow to avoid infinite loops. The final URL in the chain is the one that actually returns the page content.
Handle it deliberately in production scrapers -- most breakage traces back to skipping this step.
USER-country-de-session-task01Add this string to your scraper's proxy credentials and every request in the job shares one exit IP, which keeps redirect chain-related behavior consistent across the run. Change "task01" per worker to isolate parallel scrapes.
Isolate the logic for this step so every scraper in the project shares one tested implementation.
Sites change layouts and behavior over time -- recheck this part of the scraper on a schedule, not just at launch.
This works best over residential or ISP IPs, so the target sees ordinary browsing rather than clustered datacenter traffic.
Capture what actually failed so a broken selector or a new status code surfaces instead of getting masked by automatic retries.
A shortened marketing link redirects through three separate URLs before landing on the final product page.
Long redirect chains slow down scraping jobs and add extra requests that count against rate limits, so tracking chain length helps with performance tuning. Scrapers also need to log the final URL after all redirects, since that is usually the correct source for citing or storing scraped data.
Most browsers and scraping libraries stop after around 20 redirects and return an error, since an endless chain usually signals a misconfigured server or a redirect loop.
Marketers use redirect chains to track clicks across multiple systems, such as an email platform, an analytics tool, and finally the destination page, with each hop logging data about the click.
