HTTP3/QUIC Protocol Support

Evomi Residential Proxies support HTTP3/QUIC for improved performance and compatibility with modern websites. This feature helps requests use the same current web protocols supported by modern browsers.

Why HTTP3/QUIC Matters Permalink to Why HTTP3/QUIC Matters

Modern browsers automatically negotiate HTTP3 connections, and websites increasingly rely on this capability. HTTP3/QUIC support helps automated workflows maintain protocol compatibility with sites that use current web standards.

Key Benefits Permalink to Key Benefits

• Modern Browser Compatibility: Supports the HTTP3 capabilities available in current browsers
• Enhanced Performance: Reduced latency and improved connection reliability
• Future-Proof: Support for the latest web protocol standards
• Consistent Protocol Behavior: Reduces compatibility differences when a website expects HTTP3 support

Implementation Permalink to Implementation

Append _http3-1 to your proxy password to enable HTTP3/QUIC protocol support. Use the SOCKS5 protocol:

socks5://testuser:[email protected]:1002

Examples Permalink to Examples

# Using SOCKS5 protocol with UDP hostname for HTTP3
curl --socks5 udp.evomi.com:1002 -U testuser:testpassword_http3-1 https://ip.evomi.com/s


# Combined with geographic targeting
curl --socks5 udp.evomi.com:1002 -U testuser:testpassword_country-US_http3-1 https://ip.evomi.com/s

import requests
from requests.auth import HTTPProxyAuth

proxies = {
"http": "socks5://udp.evomi.com:1002",
"https": "socks5://udp.evomi.com:1002"
}
auth = HTTPProxyAuth("testuser", "testpassword_http3-1")
response = requests.get("https://ip.evomi.com/s", proxies=proxies, auth=auth)
print(response.text)

const fetch = require('node-fetch');
const { SocksProxyAgent } = require('socks-proxy-agent');

const proxyUrl = 'socks5://testuser:[email protected]:1002';
const agent = new SocksProxyAgent(proxyUrl);
const url = 'https://ip.evomi.com/s';

fetch(url, { agent })
.then(res => res.text())
.then(body => console.log(body));

Technical Details Permalink to Technical Details

• Protocol: HTTP/3 over QUIC (UDP-based)
• TLS: Integrated TLS 1.3 encryption
• Multiplexing: Stream-level multiplexing without head-of-line blocking
• Connection Migration: Robust connection handling across network changes
• Protocol Requirement: SOCKS5 protocol only (not compatible with HTTP/HTTPS proxies)

Common Use Cases Permalink to Common Use Cases

• Web Data Collection: Work with websites that prefer or require modern protocols
• Browser Automation: Maintain current browser protocol compatibility
• Performance Testing: Evaluate HTTP3 performance characteristics
• Security Research: Test HTTP3-specific security implementations
• E-commerce Monitoring: Monitor modern storefronts that use HTTP3
• SEO Analysis: Crawl websites using current transport protocols
