## Tutorials

- [Use a proxy with curl](https://ipvolt.com/guides/curl-proxy-setup.md): Test an HTTP proxy with curl, separate proxy authentication from destination authentication, and read connection failures without exposing credentials.
- [Configure a proxy in Python Requests](https://ipvolt.com/guides/python-requests-proxy.md): Make a Python Requests proxy configuration explicit, encode credentials correctly, and distinguish connect and read timeouts from a total job deadline.
- [Use a proxy with Node.js fetch](https://ipvolt.com/guides/nodejs-fetch-proxy.md): Route Node.js native fetch through an Undici ProxyAgent with explicit authentication, an abort deadline and response cleanup.
- [Configure a proxy in Playwright](https://ipvolt.com/guides/playwright-proxy-setup.md): Set an authenticated HTTP proxy for a Playwright browser context, keep test state isolated, and diagnose navigation separately from subresources.
- [HTTP vs SOCKS5 proxies: choose by the connection](https://ipvolt.com/guides/http-vs-socks5-proxies.md): Compare HTTP CONNECT and SOCKS5, understand DNS placement and TLS boundaries, and select a protocol your actual client and provider support.
- [Rotating vs sticky proxies: plan for session continuity](https://ipvolt.com/guides/rotating-vs-sticky-proxies.md): Choose rotation around the smallest complete workflow, distinguish exit affinity from cookies, and test what happens when a sticky session ends early.
- [Fix proxy error 407 without guessing](https://ipvolt.com/guides/fix-proxy-error-407.md): Diagnose Proxy Authentication Required in a repeatable order: gateway, authentication method, credential encoding, account scope and client configuration.
- [Mobile vs residential proxies: build a useful evaluation](https://ipvolt.com/guides/mobile-vs-residential-proxies.md): Compare carrier and household exit networks for QA, keep browser emulation separate, and measure the capabilities your workflow actually needs.
- [Proxy environment variables: HTTP_PROXY and NO_PROXY](https://ipvolt.com/guides/proxy-environment-variables.md): Diagnose HTTP_PROXY, HTTPS_PROXY, ALL_PROXY and NO_PROXY routing differences in curl, Python Requests and Node.js with an isolated local check.
- [Troubleshoot proxy timeouts one stage at a time](https://ipvolt.com/guides/proxy-timeout-troubleshooting.md): Separate proxy DNS, TCP, CONNECT, TLS and response delays with curl timings, then set request deadlines and decide whether a retry is safe.
- [Netherlands proxies: location and carrier checks](https://ipvolt.com/guides/netherlands-proxies.md): Evaluate Netherlands proxies with Dutch network context, exit-IP and city checks, ASN evidence, and a practical trial checklist before choosing a provider.
- [USA proxies: regions, networks and testing](https://ipvolt.com/guides/usa-proxies.md): Evaluate USA proxies by country, state and city. Compare network evidence, plan regional checks and measure session behavior before choosing a provider.
- [UK proxies: networks, regions and location checks](https://ipvolt.com/guides/uk-proxies.md): Evaluate UK proxies with current carrier context, UK and GB geography, postcode limitations and a practical test plan for country or network requirements.
- [Germany proxies: networks, cities and regional checks](https://ipvolt.com/guides/germany-proxies.md): Evaluate Germany proxies with current carrier and roaming context, city-location limits, browser-language controls and a practical acceptance checklist.
- [France proxies: networks, regions and local testing](https://ipvolt.com/guides/france-proxies.md): Evaluate France proxies with carrier and brand distinctions, mainland and overseas scope, exit-IP evidence, and a practical localization test matrix.
- [HTTPX async proxies: setup and PoolTimeout diagnosis](https://ipvolt.com/guides/httpx-async-proxy.md): Configure an HTTPX async proxy client, close streamed responses correctly, and reproduce a PoolTimeout locally before changing your proxy settings.
