# HTTP_PROXY / HTTPS_PROXY in Python: the pitfalls nobody documents.
#
# 1) requests reads env vars ONLY if trust_env is True (default) — and
#    HTTPS_PROXY must still be an http:// URL (it's the scheme of the
#    *target*, not of the proxy).
# 2) NO_PROXY beats both — a stray NO_PROXY=* silently disables everything.
# 3) urllib/requests lowercase vs uppercase: both are read, lowercase wins.
#
# Proxy used in the example: QuantumProxies rotating residential
# https://quantumproxies.io/rotating-proxies (creds: app.quantumproxies.io/register)

// C# HttpClient behind an authenticated residential proxy (.NET 6+).
//
// Notes that save you an afternoon:
// - WebProxy + NetworkCredential handles the 407 dance automatically.
// - Reuse ONE HttpClient; a new handler per request leaks sockets.
// - Geo flags live in the proxy username (-country-de, -session-x1-lifetime-10).
