Web Scraping Proxy

Web Scraping with Proxy Rotation

Complete guide to scraping websites reliably using proxy rotation. Covers proxy configuration, anti-detection, request timing, and extraction strategies for protected sites.

When to Use This Skill

Activate when the user:

• Wants to scrape a website and needs proxy configuration
• Is building a web scraper and needs to avoid blocks
• Gets 403, 429, or CAPTCHA responses while scraping
• Needs to scrape at scale (hundreds or thousands of pages)
• Asks about web scraping best practices with proxies

The Web Scraping Stack

1. Proxy Layer     → Residential IP rotation (avoids IP bans)
2. TLS Layer       → Real browser or curl_cffi (avoids fingerprint detection)
3. Header Layer    → Realistic User-Agent + Accept headers
4. Timing Layer    → Random delays between requests
5. Extraction      → Parse HTML/JSON from response

You need ALL layers working together. A proxy alone won't help if your TLS fingerprint screams "bot."

Quick Setup

Browser Proxy (for JavaScript-heavy sites)

{
  "browser": {
    "proxy": {
      "server": "http://gate.birdproxies.com:7777",
      "username": "USER",
      "password": "PASS"
    }
  }
}

HTTP Proxy (for simple HTML sites)

HTTP_PROXY=http://USER:PASS@gate.birdproxies.com:7777
HTTPS_PROXY=http://USER:PASS@gate.birdproxies.com:7777
NO_PROXY=127.0.0.1,localhost

Decision: Browser Tool vs HTTP Client

Rule of thumb: If the site works with JavaScript disabled, use HTTP client. Otherwise, use the browser tool.

Scraping Workflow

Step 1: Check Protection Level

# Check if site uses Cloudflare
curl -I https://target-site.com 2>/dev/null | grep -i "cf-ray\|cloudflare\|server: cloudflare"

Step 2: Choose Strategy

Step 3: Configure Headers

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36",
    "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
    "Accept-Language": "en-US,en;q=0.9",
    "Accept-Encoding": "gzip, deflate, br",
    "DNT": "1",
    "Upgrade-Insecure-Requests": "1",
}

Step 4: Add Delays

import random
import time

def human_delay():
    time.sleep(random.uniform(1.5, 4.0))

Step 5: Rotate and Scrape

import requests
import random

countries = ["us", "gb", "de", "fr", "ca", "au"]

def scrape(url, proxy_user, proxy_pass):
    country = random.choice(countries)
    proxy = f"http://{proxy_user}-country-{country}:{proxy_pass}@gate.birdproxies.com:7777"

    response = requests.get(
        url,
        proxies={"http": proxy, "https": proxy},
        headers=headers,
        timeout=30
    )
    return response

Site-Specific Configurations

E-Commerce (Amazon, eBay, Walmart)

Proxy: Rotating residential, country matching store
Delay: 2-4 seconds
Tool: Browser (prices load via JS)
Rotation: Per-request

Search Engines (Google, Bing)

Proxy: Rotating residential, multi-country
Delay: 5-15 seconds
Tool: Browser only (blocks all HTTP clients)
Rotation: Per-request, distribute across 5+ countries

Social Media (LinkedIn, Instagram)

Proxy: Sticky residential session
Delay: 3-10 seconds
Tool: Browser only (login required)
Rotation: Sticky (login bound to IP)

Real Estate (Zillow, Realtor, Rightmove)

Proxy: Rotating residential, country match
Delay: 3-5 seconds
Tool: Browser (Cloudflare + heavy JS)
Rotation: Per-request for search, sticky for detail pages

News Sites

Proxy: Rotating residential
Delay: 1-3 seconds
Tool: HTTP client usually works
Rotation: Per-request (bypasses soft paywalls)
