/**
 * Symfony HttpClient with proxy example.
 *
 * Configuration via environment variables:
 *   PROXY_URL  - Proxy URL (required), e.g., http://user:pass@proxy:8080
 *   TEST_URL   - URL to request (default: https://api.ipify.org?format=json)
 *
 * Symfony HttpClient is a modern, PSR-18 compatible HTTP client.
 * It supports proxies but does NOT support custom CONNECT headers or
 * reading proxy response headers.
