What is a rotating proxy and how does IP rotation work
A rotating proxy assigns a different exit IP to your traffic automatically. You keep sending requests to the same gateway endpoint with the same credentials; the gateway decides which address in the pool actually makes each request.
The two rotation modes
Per request. Every single request leaves from a different IP. This is the default for high-volume collection where each page is independent — price lists, search results, product pages.
Timed (sticky). The same IP is held for a fixed window, typically a few minutes, then swapped. Use this whenever the target site sets a session cookie, runs a multi-step checkout, or logs you in. See What is a sticky session and when should I use one.
Why rotation helps
Rate limits are almost always applied per IP. Spreading 10,000 requests over thousands of addresses keeps each address well under the threshold that triggers a block, so you are never asking one IP to look like a person browsing at machine speed.
What rotation does not fix
Rotation only changes the network layer. If your requests carry the same cookie, the same browser fingerprint or the same unrealistic header order, the site can still link them together. Rotate the IP and keep the rest of the request believable.
