When using a proxy IP, "rotating session" and "sticky session" are the two common modes, but many businesses aren't sure which fits their needs. This short guide breaks down the difference and when to use each.
The Difference
Rotating sessions automatically switch to a new IP with every request — good for tasks that need to switch access viewpoints quickly and cover a large number of samples.
Sticky sessions keep the same IP for a set period of time — good for tasks that need to maintain a login state or complete a multi-step process.
Best-Fit Scenarios
Rotating sessions work better for:
- Large-scale market research covering many sites or regions
- SEO ranking monitoring, quickly switching viewpoints to get search results across regions
- Ad display verification across multiple regions
Sticky sessions work better for:
- Multi-step workflows that need to maintain a login state
- Visiting multiple pages on the same target site within one task
- Completing a full verification flow under the same identity
How to Decide
The rule of thumb is simple: if the task needs "breadth" (covering many samples), go with rotating; if it needs "continuity" (maintaining the same identity across multiple steps), go with sticky. When unsure, you can also use both modes for different parts of the same workflow.
