When using the commands listed in the Bright Data Proxy Manager GitHub page, the "requests per session" parameter is defined by using:--max_requests Requests per session [default: 50].
Our API allows you to manage the rotation on your end by using the session parameters. This can be done by adding the session to the proxy username:lum-customer-YOUR_CUSTOMER_ID-zone-YOUR_ZONE-session-rand39484
Changing the session number changes the IP as well.
IP rotation can also be managed through the Proxy Manager dashboard editing under IP Policy.
