For sites with multiple redirection layers, I track URLs before and after redirects to identify any patterns and adjust my scraper accordingly.

I monitor error codes, like 429 (Too Many Requests), to detect rate limits in real time. My script pauses or retries after a delay when it sees this code.

I use a database to track which dates have been scraped, so I don’t duplicate efforts or miss any dates.

Adding delays between form submissions is essential to avoid detection, especially if the site monitors activity.
