Operating guide

Validate localized prices through regional proxies with controlled locale, session, product, tax, currency, and checkout evidence before using the data for market research.

Test DNS HTTPS and SVCB behavior across direct, HTTP CONNECT, SOCKS local-DNS, and SOCKS remote-DNS routes without confusing resolver differences with proxy quality.

Detect stale cached responses in proxy data collection with Age, Date, Cache-Control, validators, body digests, controlled revalidation, and multi-region comparisons.

Prevent clock drift and time jumps from corrupting proxy latency and session metrics. Build a dual-clock schema, test time-step behavior, and validate multi-region evidence.

Normalize IPv4-mapped IPv6 addresses in proxy logs without losing audit evidence. Use strict parsing, canonical identity keys, test cases, and before-and-after metrics.

Test concurrent residential proxy session isolation with controlled labels, fresh connections, exit hashes, collision metrics, and acceptance thresholds.

Test TLS session resumption safely across sticky and rotating proxy paths while preserving trust, tenant and request boundaries.

Measure proxy connection idle age and total lifetime, detect stale reuse, and choose safe pool limits without destroying useful keep-alive performance.

Test whether proxy clients recover from transient DNS failures without confusing them with authoritative negative answers or connection-cache effects.

Test complete LDAP SASL authentication across direct and approved proxy routes, identify the narrow OpenLDAP exposure, and verify curl 8.22 remediation.
