When you scrape at any real volume, the bottleneck is rarely your code — it's the target site's rate limiting and IP bans. Rotating residential proxies solve this by routing each request through a different real-user IP. Here's how to wire them into requests and Scrapy in Python, including the sticky-session trick most tutorials skip.
The proxy URL format
A residential proxy is just an authenticated HTTP/SOCKS endpoint. With a pool gateway, you target a country and control session behavior through the username, not separate endpoints:
http://USERNAME_country-us_session-a1b2c3_lifetime-30:PASSWORD@proxy.gproxy.net:1000
