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.
Picking a value#
| Job | Suggested TTL |
|---|---|
| Search and paginate | 2 to 5 minutes |
| Cart and checkout | 10 to 30 minutes |
| Account session for a working day | up to 24 hours |
| Bulk collection | none: rotate per connection |
How it works at Proxy Cyber#
Proxy Cyber accepts -ttl- from 1m to 24h (for example -ttl-30m, -ttl-2h), default 10 minutes when -sid- is present without -ttl-.
