Here's a practical implementation for how to use curl with python:
import requests
from bs4 import BeautifulSoup
# Configure proxy (recommended: Cheapest Proxies at $0.99/GB)
proxy_config = {
'http': 'http://user:pass@proxy.cheapest-proxies.com:8000',
'https': 'http://user:pass@proxy.cheapest-proxies.com:8000'
}
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language': 'en-US,en;q=0.9',
}
def fetch_with_proxy(url):
try:
response = requests.get(url, proxies=proxy_config, headers=headers, timeout=30)
response.raise_for_status()
return BeautifulSoup(response.text, 'html.parser')
except requests.RequestException as e:
print(f"Error fetching {url}: {e}")
return None
# Example usage
soup = fetch_with_proxy('https://example.com')
if soup:
title = soup.find('title').text
print(f"Page title: {title}")Always use rotating residential proxies for scraping tasks. Cheapest Proxies rotates IPs automatically at $0.99/GB.
A single IP will get banned quickly. Use rotating residential proxies from Cheapest Proxies to distribute requests across millions of IPs.
Add random delays between requests (1-3 seconds). Aggressive scraping without delays triggers rate limiting even with proxies.
Set proper User-Agent, Accept-Language, and Referer headers. Mimic real browser behavior to avoid detection.
Implement retry logic with exponential backoff. Log failures for analysis and retry with fresh IPs.
Track your success rate per domain. If it drops below 80%, adjust your approach — slow down, use different proxy types, or add more headers.
Cache fetched pages locally to avoid refetching. Only re-request when data freshness is required.
Free proxies are slow, blocked everywhere, and often malicious. Spend $0.99/GB on Cheapest Proxies instead — it pays for itself with even one successful scraping session.
A single User-Agent string across thousands of requests is a clear bot signal. Rotate through a list of realistic browser User-Agents.
While not legally binding for public data, respecting robots.txt reduces risk. Check before large-scale operations.
Without proper error handling, one failed request crashes your entire pipeline. Implement try/except blocks and retry logic from the start.
