Rotation

MarsProxies residential proxies support two session rotation modes: Sticky and Randomize. Each mode is designed for different use cases, so you can choose the one that best fits your workflow.

Sticky

Sticky sessions let you hold onto the same proxy IP for a set period of time. This is useful when your task requires a continuous connection from the same address — for example, when interacting with websites that use session-based authentication or track your activity across multiple requests.

Two parameters control how sticky sessions work:

• _session- — Tells the routing system to create or maintain a specific session. The value must be a random alphanumeric string that is exactly 8 characters long, which guarantees each session is unique.

• _lifetime- — Sets how long the session stays active. The minimum is 1 second and the maximum is 7 days. Keep in mind that only a single time unit can be specified per value.

Example:

ultra.marsproxies.com:44443:username123:password123_country-br_session-fsiwjtqc_lifetime-10m

Randomize

With randomized rotation, a fresh proxy IP is assigned on every request. This makes it the ideal choice for tasks that demand a high degree of anonymity, such as web scraping or browsing without a traceable pattern.

No additional parameters are needed in your proxy string to use this mode — it works out of the box.

To reduce IP rotation frequency and improve proxy performance, add the _forcerandom-1 tag to your proxy string. This expands the pool of available IPs to select from.
