Rotating & Sticky Sessions
FlashProxy gives you two ways to control the IP behind your requests.
Rotating
A fresh IP for every request. Best for high-volume work — scraping, crawling, price monitoring — where you want maximum IP diversity and don't care which IP serves any single request.
Sticky
The same IP persists across multiple requests. Use it when a workflow has to keep one identity — logins, multi-step flows, cart sessions, account warming. How long an IP holds depends on the product:
- Residential & mobile pools (Residential, Mobile, Unlimited Residential): the IP sticks until the device rotates off the pool — typically up to ~2 hours. You don't set an exact lifetime; the pool's device availability governs it.
- ISP (US & EU), Datacenter, and IPv6 (large shared pools): hold an IP for as long as you need, or pin a specific IP from the pool with the IP-targeting flag -ip-0_0_0_0 in your username (see Geo-targeting).
- Dedicated ISP: you own the IP — every request exits that same static IP. There's nothing to pin or rotate; persistence is built in.
Which products support sticky
Most products support both rotating and sticky: Residential, Datacenter, Mobile, Shared ISP (US & EU), Dedicated ISP, IPv6 Residential, IPv6 Datacenter, and Unlimited Residential.
Exception: Residential Lite is rotating-only — it does not offer sticky sessions.
When to use each
| Goal | Session type |
|---|---|
| Maximum IP diversity, high request volume | Rotating |
| Keep one identity across a multi-step flow | Sticky |
| Price-sensitive, high-volume jobs (Residential Lite) | Rotating only |
Note: Choosing a session type is done through your connection settings — see the per-product guides and Geo-targeting for how options combine in the username.
