# Common Note

A transient proxy (also known as helper pod) is brought up for a [chaos duration](/resilience-testing/chaos-engineering/faults/chaos-fault-categories/common-tunables-for-all-faults.md) to intercept the requests made from the target application to another service and elsewhere, and inject chaos accordingly. Target application refers to the application pods calling/sending egress traffic to an endpoint.
