How caching, circuit breakers, retries, and rate limiting absorb unreliable proxy networks.

Resilience

Public proxy pools are volatile. ProxyWhirl layers four resilience mechanisms so applications keep making progress without manual babysitting.

Components

Layer	Role
Cache	Reduce repeated fetches and validation work
Circuit breaker	Stop routing through proxies that fail repeatedly
Retry	Back off and try alternate proxies on transient errors
Rate limiting	Cap request velocity to protect upstreams
