What is Sticky Session?
A configuration that keeps the same proxy IP for a defined period (up to 72 hours with seamless), used when a task needs a consistent identity such as a login or checkout.
A sticky session pins one exit IP to one session for a fixed window. Every request you send with that session identifier leaves from the same address, so a site following you through a multi-step flow sees one coherent visitor.
This is required for anything stateful. Logging in, filling a cart, completing a checkout, paginating through results behind a session cookie — all of it breaks or triggers a security check if the IP changes mid-flow.
Sessions are normally selected through the proxy username, with a session identifier and a duration appended to it. Change the identifier and you get a new IP; keep it and you keep the address until the window expires.
