## Connection notes

### 1. Your client

cURL · Python · Node.js · Playwright

Protocol & authentication

### 2. Proxy gateway

Connection · Credentials · Session

Request & response

### 3. Destination

The service you’re connecting to

A general proxy flow. These guides are independent of any ipvolt service availability.

## Connect your stack.

Explicit configuration, bounded requests and a clear way to verify the connection.

- [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. (4 min read)
- [Configure 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. (4 min read)
- [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. (4 min read)
- [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. (4 min read)
- [HTTPX async proxies](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. (7 min read)

## Understand the tradeoffs.

Choose a protocol, session model or network type with the right questions in mind.

- [HTTP vs SOCKS5 proxies](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. (4 min read)
- [Rotating vs sticky proxies](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. (4 min read)
- [Mobile vs residential proxies](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. (4 min read)

## Find the failure.

Separate authentication, connectivity and destination errors before changing your setup.

- [Fix proxy error 407](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. (4 min read)
- [Proxy environment variables](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. (6 min read)
- [Diagnose proxy timeouts](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. (9 min read)

## Check the location.

Understand local networks, verify exit locations and ask better questions before choosing a provider.

- [Netherlands proxies](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. (9 min read)
- [USA proxies](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. (9 min read)
- [UK proxies](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. (9 min read)
- [Germany proxies](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. (9 min read)
- [France proxies](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. (9 min read)

## About this library

Examples use generic proxy settings, with links to the original technical documentation. Product-specific behavior must be checked with your provider. ipvolt is still in development.
