## Goal
Talk to HTTP services without hanging, leaking connections or misreading responses.

## Prerequisites
A choice of client: `urllib.request` from the standard library for simple needs, or a client library such as httpx for connection pooling, HTTP/2 and async use.

## Steps
1. Always pass a timeout; the default of no timeout can block a process forever on a silent peer.
2. Identify your client with a `User-Agent` and state what you accept with `Accept`.
3. Reuse one client object for many requests so that connections are pooled and TLS is not renegotiated each time.
4. Treat status codes as the primary signal: 2xx success, 3xx follow only when safe, 4xx do not retry (fix the request), 5xx/429 retry with backoff and `Retry-After`.
5. Decode bodies using the declared content type and charset; for JSON, parse only when the media type says JSON.
6. Send conditional requests (`If-None-Match`) for polling and honour `Cache-Control`.
7. Never place credentials in URLs; use headers, and do not follow redirects to other hosts with credentials attached.

## Expected result
Requests fail fast on dead peers, succeed efficiently against live ones, and errors are classified rather than swallowed.

## Limits and test basis
Retries duplicate non-idempotent requests unless an idempotency key is used. Proxies and corporate networks add their own timeouts and TLS interception. Guidance follows the cited documentation and this wiki's example client.
