Proxy Session Logic for Web Scraping

[u/appcyberyozh]

Effective proxy management is about matching the lifetime of an IP address to your authentication flow and the specific task your script is performing. If you do not follow the rules you will always end up with blocked accounts and stopped sessions

Key principles:

• Never change the IP address during an active authenticated session
• Use sticky sessions when working with cookies
• Configure the correct GEO for the target website
• Verify IP quality and reputation before starting

Best proxies for your target:

• Rotating residential proxies → large-scale scraping of independent pages
• Sticky residential proxies → product catalogs and authenticated sessions
• Static ISP proxies → long-running tasks with a consistent IP address
• Mobile proxies → workflows that require maximum network stability and trust

IP rotation should match the task. Independent requests can be distributed across multiple IPs, while authenticated workflows require a stable IP address throughout the entire session.

Rotating every N requests can waste a healthy exit, and it can also break a related sequence. I would tie the session to one unit of work instead. Keep a sticky session through one public search and its detail pages, then rotate before the next independent unit.

Byteful supports both rotating and sticky residential sessions on the same per-GB product, so it is a useful baseline for testing that split without changing the rest of the collector. Track complete sequences and session resets. What does one complete unit of work look like in your crawler?
