What is proxy session and idle timeout?

Every proxy comes with 2 time limits: session and idle timeout

Session Timeout: The maximum amount of time (in seconds) a single proxy connection can stay running without interruptions. When timeout is reached, the proxy connection is terminated.

Idle Timeout: The maximum amount of inactivity (no data sent) before a proxy connection is terminated.

You can adjust both the session and idle timeout on the proxy settings page.
