A sticky session is a proxy configuration that maintains the same IP address for a defined period, typically 1-30 minutes. It ensures multiple related requests use the same exit IP, simulating a consistent user session.
When you create a sticky session, the proxy network assigns you an IP from its pool and reserves it for a set duration. All requests tagged with the same session identifier route through that IP. After the session expires, the next request gets a new IP. Providers typically implement sticky sessions through special username parameters (e.g., user-session-abc123) or API settings.
This is largely a plan and configuration choice, not a technical limitation.
USER-sticky-session-task01Everything lives in the username -- add "sticky" to any proxy credential to apply sticky session to a single task. Swap "task01" for a new label to spin up an independent, isolated identity.
KnoxProxy sticky sessions persist up to 30 minutes on residential (60 on mobile), and the window refreshes with activity.
Each session or connection label gets its own exit, so parallel identities never collide.
This costs nothing beyond bandwidth -- successful responses are billed, not the session or connection itself.
Run as many parallel sessions or connections as the job needs -- concurrency is not capped on any plan.
A price monitoring tool creates a 5-minute sticky session for each target website so the site sees consistent browsing behavior: homepage, category page, product page, all from the same IP.
Sticky sessions let you maintain the same IP across multi-step workflows while still using a rotating proxy service. They bridge the gap between full rotation and fully static proxies.
Most providers offer sticky sessions from 1 minute to 30 minutes. Some support up to 60 minutes. Longer durations may not be guaranteed because the exit node can go offline. For extended IP persistence, use static proxies.
The proxy network releases the IP back to the pool. Your next request gets a new IP from the pool. To continue with the same identity, create a new sticky session (which may get a different IP).
Some providers automatically extend the session while requests are active. Others have a hard timeout. Check your provider documentation for session renewal policies.
