Naproxy's design philosophy from the crawler case
Why do we need rotating IP?
In data collection scenarios:
High-frequency requests will trigger anti-crawling mechanisms (such as IP current limiting)
Some content is displayed differently according to geographical location
The target website actively blocks abnormal IPs
Limitations of common solutions
We have tested:
Tor network: automatic IP switching but extremely slow (<50KB/s)
Self-built proxy pool: manual maintenance of IP list, complex concurrency control
Cloud function solution: high latency caused by cold start of each request
Engineering implementation of Naproxy
Transparently handle IP rotation through the protocol layer:
# Python crawler integration example
import requests
for url in target_urls:
# Use Naproxy's rotation endpoint
response = requests.get(
url,
proxies={"https": "socks5://rotator.naproxy:1080"}
)
# Automatically assign a new IP for each request
System workflow:
Crawler request sent to Naproxy scheduler
Select residential IP/mobile IP pool according to strategy
Allocate corresponding IP resources according to target country
Automatically eliminate invalid nodes and add new IP
Actual effect comparison (real estate data crawling project):
Available amount of effective IP: increased from 1,200 per day to 18,000+
Request success rate: 76% for self-built solution → 98.3% for Naproxy solution
IP replacement speed: 2-6 hours for manual operation → <3 minutes for automatic system replacement
Which scenarios are not applicable?
After half a year of production verification:
Scenarios that require deep customization of TCP protocol
Ultra-large-scale traffic (1 billion+ requests per day)
Large-bandwidth applications such as video streaming
Recommended scenarios:
Business prototypes that require rapid verification
Small and medium-scale data collection projects
Teams with existing cloud native infrastructure
