Sticky Proxy

A sticky proxy session (also called "session proxy") keeps the same IP address for the duration of a session, typically 5 to 30 minutes. This is essential for actions that require state consistency across multiple requests, like logged-in browsing, checkout flows, or multi-step forms.

Sticky sessions are standard for residential proxy providers and allow you to balance between rotation (for anti-detection) and consistency (for session-based workflows).

How it works

A sticky session is identified by a session id embedded in the proxy username, for example USER-session-a8f2. The first request with that id makes the gateway pick a peer IP from the pool and pin it to that id. Every subsequent request carrying the same id is routed through the same peer, even if you send it minutes later from a different machine. When the session expires (default 30 minutes on Murphy) or the peer goes offline, the next request with that id gets a fresh IP.

The pattern works for the obvious case (a logged-in scraper that needs cookies to survive across page loads) and for less obvious ones too: solving a CAPTCHA from one IP and reusing the token on the next page, running a Playwright session across navigation events, completing a multi-step checkout, or keeping a single account associated with a single IP for social-media automation. Combine country/city filters with the session id to pin a specific geo to a specific session.
