Both modes use the same underlying residential network. The difference is purely about how long any given IP stays attached to your traffic. Rotation maximizes variety; stickiness maximizes continuity. Almost every workflow leans toward one or the other, and the trick is matching the mode to what the target site expects from a normal user.
Rotating proxies: a new face every time
With rotation, each request can go out through a different residential IP. From the destination's perspective, no single address is doing very much, so nothing stands out as automated volume. This is ideal when your requests are independent of one another — fetching a thousand product pages, sampling search results across regions, or polling public listings. Because no IP accumulates a suspicious request history, rotation is the default for high-volume collection.
The catch is state. If a site sets a session cookie, builds a cart, or tracks a login, rotation breaks that continuity: request two arrives from a stranger's IP and the site reasonably treats it as a new visitor. For anything that has to remember who you are between requests, rotation works against you.
Sticky sessions: one consistent identity
A sticky session pins a single IP to your traffic for a set window — on our network, anywhere from 10 to 180 minutes. Everything you do during that time appears to come from one household, which is exactly what a real logged-in user looks like. Sign in, navigate, add to cart, submit a form, walk a multi-step funnel — all from a stable address that doesn't change underneath you.
You choose the hold duration when you generate the proxy, so you can match it to the task: a short window for a quick login check, a longer one for a workflow that spans many minutes. When the window ends, you simply generate a fresh session if you need to keep going.
Side by side
| Trait | Rotating | Sticky |
|---|---|---|
| IP per request | Changes each request | Held 10–180 min |
| Best for | Bulk, independent requests | Logins & multi-step flows |
| Session state | Not preserved | Preserved within the window |
| Footprint per IP | Minimal — spread wide | Concentrated on one IP |
| Typical job | Scraping, sampling, monitoring | Checkout, account, funnel QA |
A simple rule of thumb
Ask whether the site needs to remember you between requests. If the answer is no — you're reading public pages and each fetch stands alone — rotate. If the answer is yes — there's a login, a cart, or a sequence that must hang together — go sticky for the duration of that sequence. Plenty of real projects use both: rotating to discover URLs at scale, then sticky to act on a few of them with a consistent identity.
Whichever mode you pick, it only pays off on clean IPs. A flagged address starts the request already losing, rotating or not — so pair either mode with clean residential proxies. New to the basics?
