Common Protocols

• HTTP/HTTPS — Browsers & HTTP(S) clients.
• SOCKS4/5 — Generic TCP proxying for apps & scripts.

Best Practices

• Rotate IPs for higher success on rate-limited targets.
• Respect robots.txt, rate limits & site terms.
• Use timeouts and retries with backoff.
• Log failures and replace slow or unstable hosts.

Quick Examples

curl -x http://USER:PASS@HOST:PORT https://httpbin.org/ip

import requests

proxies = {
  "http":  "http://USER:PASS@HOST:PORT",
  "https": "http://USER:PASS@HOST:PORT"
}
r = requests.get("https://httpbin.org/ip", proxies=proxies, timeout=20)
print(r.json())
