Overview

HTTPX 0.27, released on February 22, 2024, improves connection pool management and adds SOCKS proxy support.

Main Features

Connection pool

The connection pool is optimized with better HTTP/2 connection reuse and finer limit control.

python 
import httpx

# Configured connection pool
limits = httpx.Limits(
    max_connections=100,
    max_keepalive_connections=20,
)

async with httpx.AsyncClient(limits=limits) as client:
    response = await client.get('https://httpbin.org/get')
    print(response.status_code)  # 200

SOCKS support

HTTPX supports SOCKS4 and SOCKS5 proxies via the socksio package, enabling routing through Tor or VPNs.

python 
import httpx

# pip install httpx[socks]
client = httpx.Client(
    proxy='socks5://127.0.0.1:1080',
)

response = client.get('https://httpbin.org/ip')
print(response.json())  # proxy IP
client.close()
