A web server is like a supermarket cashier who slips you aMembership Card (Session Cookie). Even if you enter the store wearing a different mask (proxy IP), as long as you pull out the same membership card, the cashier immediately knows it's an old acquaintance. What's morePersistent Cookie, you can be recognized even if you change your device.

 Typical Cookie Carrying Example (Python)
import requests
proxies = {"http": "http://username:password@proxy.ipipgo:8080"}
cookies = {"user_token": "a1b2c3d4e5"}

response = requests.get(

Pitfalls in the real world and a guide to avoiding mines

Recently, when I helped a customer to do an e-commerce price comparison system, I stepped on a big thunderbolt: I used a dynamic residential proxy to catch data, and I changed a dozen IPs, but the result was still a ban.Browser FingerprintingIt wasn't handled cleanly and the cookie carried the device resolution information. The solution is to enable in the ipipgo clientUA randomized mode, in conjunction with the automatic switching of proxies.

// Node.js version of the solution
const ipipgoProxy = 'socks5://user:pass@gateway.ipipgo:1080';
const puppeteer = require('puppeteer');

async function stealthMode() {
  const browser = await puppeteer.launch({
    args: [`--proxy-server=${ipipgoProxy}`]
  });
  const page = await browser.newPage();
  await page.setUserAgent('Randomized UA string');
  // Remember to request the UA randomization service in the ipipgo backend.
}
