Operating guide

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.

Test whether pooled libcurl TLS connections safely outlive easy handles when OpenSSL 3 providers are configured, then verify a curl 8.22 rollout.

Scope and regression-test HTTP/2 server push cleanup in shared libcurl connection pools without unsafe traffic or credential exposure.

Test whether browser, client, service-worker, gateway, CDN, or application caches mix responses across proxy sessions, locations, languages, and accounts.

Build a useful proxy support escalation packet with reproducible tests, timestamps, error taxonomy, redaction, and no exposed credentials.

Design and test isolated TLS trust profiles for reused proxy clients, including pool keys, negative tests, safe rollout, and evidence collection.

Test a proxy client circuit breaker with failure classification, market isolation, half-open probes, retry budgets and fail-closed verification.

Test country, state, city and ZIP residential proxy targeting with an acceptance matrix covering accuracy, capacity, latency, sessions and cost.

Build an authorized residential proxy test matrix for localized ecommerce checkout, covering IP market, address changes, currency, tax, shipping and privacy.
