Rotating and sticky describe how long you keep an exit IP. A rotating session hands you a fresh IP on every request; a sticky session pins one IP for a set window. Both run on the same gateway — you choose per request — and picking right is the difference between getting blocked and staying logged in.
Rotating sessions
By default the gateway rotates: each request exits through a new IP. That spreads traffic across the pool, so no single address accumulates suspicious volume — ideal for crawling many pages, checking SERPs, or sampling prices, where each request stands alone.
Rotation is the safest mode for high-volume reads. The downside is that anything requiring continuity — a login, a cart, a multi-step form — breaks when the IP changes mid-flow.
Sticky sessions
A sticky session holds one exit IP for up to 30 minutes, so a sequence of requests shares a single identity. Use it for logins, checkouts, account actions and any workflow where the target expects the same visitor across steps.
On this network you create one by adding a session id to your username (sessid) and optionally a time-to-live (sessttl) in minutes; the gateway keeps returning the same IP until the window expires. Pull a new session id when you want a fresh sticky IP.
