Operating guide

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.

Compare SOCKS5 and HTTP/HTTPS proxies with a controlled protocol, DNS, authentication, IPv4/IPv6, performance and failure-handling test matrix.

Run a controlled acceptance test for shared and dedicated proxy plans using latency, throughput, error, reputation, route stability and cost evidence.
