Manually updating lists is tedious. Use a cron job or a simple Node script:
import fetch from 'node-fetch'; import fs from 'fs';async function updateProxyList() const res = await fetch('https://api.proxyscrape.com/v2/?request=displayproxies&protocol=http&timeout=5000'); const proxies = (await res.text()).split('\n').filter(p => p.trim()); fs.writeFileSync('proxies.json', JSON.stringify(proxies, null, 2));
// Run every 15 minutes setInterval(updateProxyList, 15 * 60 * 1000);
Free proxies are inherently unstable. To maximize success with your "reflect4 proxy list free upd", tweak Reflect4’s configuration file (usually reflect4.conf):
[Proxy Settings]
threads = 50 ; Lower if you see many timeouts
timeout = 7 ; Standard for free proxies (in seconds)
retry_on_failure = 2 ; Retry once before discarding
anonymity_level = 2 ; 0=All, 1=Anonymous, 2=Elite (stick to 2)
output_format = ip:port
auto_update_interval = 3600 ; Check for new free upd every hour
Even with a "free upd" source, 30-40% of proxies may fail due to timeout or DNS errors. Reflect4 has a built-in checker, but you should pre-validate. Here is a quick method using curl on Linux/Mac or WSL:
while read line; do
curl -s -x "http://$line" "http://httpbin.org/ip" --max-time 5
done < reflect4_proxy_list.txt
If you get a JSON response containing "origin": "YOUR_PROXY_IP", the proxy works. reflect4 proxy list free upd
Several open-source projects crawl public proxies and format them for immediate use.
The legacy CZ88 proxy format is still used in many free upd circles. Use an online converter to turn CZ88 lists into a raw IP:Port list for Reflect4.
Free proxy lists go stale quickly—sometimes within hours. Here are reliable sources that provide regular updates (often every 10–60 minutes). Manually updating lists is tedious
A proxy server acts as an intermediary between a client (your computer or app) and a destination server (a website or API). When you use a proxy:
Types of proxies:
Reflect4 in some contexts refers to a tool that leverages proxy reflection or proxy chaining, where requests bounce through multiple proxies to increase anonymity or bypass geographic restrictions. However, “Reflect4” is not an industry‑standard term; be cautious of unverified software. // Run every 15 minutes setInterval(updateProxyList, 15 *
