A proxy is an intermediate server between you and a website.
Instead of: You → Website It becomes: You → Proxy → Website
Why proxies are used - distribute traffic - avoid IP-based limits - access region content - improve reliability
Important warning Proxies are tools, not magic. Do not use them to break rules.
Example: requests with proxy ```python import requests
proxies = { "http": "http://127.0.0.1:8080", "https": "http://127.0.0.1:8080" }
res = requests.get("https://example.com", proxies=proxies, timeout=10) print(res.status_code) ```

When to use proxies - scraping large scale - site limits per IP - geo-blocked pages
Remember - Use trusted proxies only - Expect slower speed - Avoid sensitive data
