Rotating and sticky sessions: what each is for

Rotating

A rotating setup gives you a different exit address, per request or per interval. It spreads a large crawl so no address repeats often. Residential proxies work this way, and the pool chooses the address.

Sticky

A sticky session keeps one address for a period, so a multi-request flow such as a login and a page load arrives from one place. Whether a line offers it, and for how long, is stated on the product page.

Static is the strongest form of sticky

An ISP or datacenter proxy keeps one address for the whole term. If an account must always appear from the same address, rent a static IP rather than hold a rotating session.

Choosing

Ask what breaks when the address changes.

1. Nothing breaks, volume is large: rotate.
2. A short flow breaks: use a sticky session where offered.
3. An account or identity breaks: use a static IP.
