Session TTL

A session TTL (time to live) is the lifetime of a sticky proxy session: the period during which requests carrying the same session identifier are routed through the same exit IP. When it elapses, the next request with that identifier gets a new exit. Lifetimes range from a minute to a day depending on the provider; longer lifetimes trade freshness for continuity.

Measured from when#

On most gateways the clock starts at the first request that used the identifier and is not extended by activity: a 30-minute TTL ends 30 minutes after the session began, whether or not requests are still flowing. Plan the lifetime around the longest flow you expect, not the average.

How it works at ProxShift#

ProxShift accepts -ttl- from 1m to 24h (for example -ttl-30m, -ttl-2h), default 10 minutes when -sid- is present without -ttl-.
