How do sticky sessions work in Python and Node.js?

When selecting 30-Min Sticky session mode, our gateway assigns a unique session ID in your username string. All subsequent requests remain pinned to the same residential IP.

Can I target specific countries or cities?

Yes! Simply append country or city parameters directly to your username string (e.g., customer-USER-country-us-city-newyork:PASS).

Why is Playwright and Puppeteer proxy authentication handled differently?

Headless browsers require configuring proxy parameters at the browser launch level, whereas Puppeteer authenticates via page.authenticate().

What are Anti-Bot Stealth Headers?

Anti-bot firewalls like Cloudflare Turnstile inspect browser Client Hints and User-Agent strings. Our stealth preset adds authentic headers to avoid bot detection.
