Rotation means "a different IP on every request", and most people automatically assume this is "better". In reality, rotation is a tool, not a goal. Used in the wrong place, it locks accounts, breaks sessions and drives up cost. This article clarifies where each of the two modes is the right one.
How the Two Modes Behave
In rotating mode the target site thinks you are a new visitor every time; in static mode it recognizes you as the same user. Both come at a price.
Comparison
The critical row is "session continuity": any job that involves a login requires static or sticky mode.
Sticky Sessions: The Middle Ground
A sticky session lets you keep the same IP in a rotating pool for a defined period of time . It works with a session key written into the username: kullanici-session-ab12 for example. As long as the same key is sent, the gateway returns the same exit IP. Typical durations are 1, 10 and 30 minutes.
The session duration must be longer than the workflow you need to complete. You cannot finish a 10-minute job with a 1-minute sticky session.
Choosing the Rotation Interval
Rotating too often makes the target site see a "flood of new visitors" and flag the whole pool as suspicious. Rotating too rarely runs you into the rate limit. The practical rule: measure how many requests per minute the target accepts, leave a safety margin, and divide accordingly.
Read the list from top to bottom: the more "session-based" the job, the longer you need to keep the same IP.
Error Handling
The real power of rotation is the ability to retry a failed request with a new identity . A solid client applies the following rules:
- 429 / 403: drop the IP and retry with a new IP after 2–5 seconds.
- 5xx: target server issue — retry with the same IP using exponential backoff.
- Timeout: proxy-side issue — change the IP and increment the counter.
- 3 consecutive failures: put that sub-pool into temporary quarantine.
To keep retries from looping forever, cap them at a maximum of 3 attempts per request; otherwise your GB budget drains without you noticing.
Do not tune without measuring: record the success rate and the average latency for each rotation interval. The Proxy Checker tool shows individual addresses, while your own logs show the pool as a whole.
To decide on the IP type at the same time, see the residential–datacenter and ISP–residential comparisons; for account-focused work, the social media proxy page contains practical examples.
