Sticky Session
A rotation setting that keeps the same IP address for a fixed period rather than changing it per request.
Sticky sessions pin your traffic to one IP for a defined window — commonly 1, 10 or 30 minutes. This matters wherever a site ties state to an address: login flows, multi-step checkouts and shopping carts all break if the IP changes mid-journey. Most providers expose stickiness through a session identifier in the proxy username.
In practice
- Completing a five-step checkout without being logged out
- Maintaining a cart across page loads
