Operating guide

Benchmark residential and rotating proxy concurrency safely. Locate the throughput knee, diagnose queueing, control retries and size workers by useful results and cost.

Audit HTTPS proxy and destination TLS separately with certificate, SNI, ALPN, DNS, route and response-integrity checks before production rollout.

Test proxy idle timeout and keep-alive behavior with controlled gaps, pooled reuse, half-open failures, session checks and evidence-based retirement settings.

Test whether proxies deliver complete and correct HTTP responses using framing checks, decoded hashes, range validation, semantic assertions, retry controls and useful-result metrics.

A practical test for comparing proxy providers by exact IP, routed prefix, ASN, geography, churn, and cost without mistaking two brands for independent capacity.

A practical WebSocket proxy acceptance test covering upgrades, CONNECT tunnels, ping/pong, idle timeout, rotation, reconnects, and message integrity.

Validate proxy DNS, authentication, tunneling, IPv4-only destination access, and failover on IPv6-only DNS64/NAT64 networks.

Validate DNS cache lifetimes, stale answers, IPv4 and IPv6 behavior, and connection reuse before a proxy gateway cutover.

Validate proxy country and region claims with multiple evidence sources, confidence tiers, freshness controls and destination-level acceptance tests.

Validate proxy credential encoding safely, distinguish parsing failures from real 407 responses, prevent double encoding and keep secrets out of logs.
