Long-lasting http proxy: long-lasting HTTP proxy maintenance program

How exactly do you keep a long-lasting HTTP proxy? Handy guide to avoid the pitfalls

engage in data collection friends should understand, long-lasting proxy with a really fragrant, but the maintenance is really bald. Today we do not whole false, directly on the dry goods to say how to HTTP proxy to maintain a stable and long-lasting.

First, find a good "nest" for the agent.

Selecting an agent is similar to finding a partner, the bottom is not good and then maintenance is useless. Those on the marketDynamic Residential AgentsIt's cheap, but it's easy to drop the line like opening a blind box. Suggest going straight to theipipgo's Static Residential PackageThe probability of running continuously for 30 days without dropping out can reach more than 87%.

 Example of Python detecting proxy survival (every 2 hours)
import requests
from apscheduler.schedulers.blocking import BlockingScheduler

def check_proxy():
    proxies = {"http": "http://username:password@gateway.ipipgo.com:9020"}
    try.
        resp = requests.get('http://ip.ipipgo.com', proxies=proxies, timeout=10)
        if resp.status_code == 200:: print("The status code of the request is not available for all requests.
            print("Proxy status is normal")
    except.
        print("Proxy is abnormal, start auto-replacement")

scheduler = BlockingScheduler()
scheduler.add_job(check_proxy, 'interval', hours=2)
scheduler.start()

Second, the daily maintenance of the three great tips

1. flow control technologyDon't gripe hard with one IP, it is recommended that a single IP request no more than 500 times per hour. ipipgo client comes with a traffic statistics function, and it will switch automatically if it is overloaded.

2. The Great Disguise: Remember to switch User-Agents randomly, here's a little trick - make the request interval airregularly distributed(e.g., 3-8 seconds randomly), which is safer than a fixed frequency

3. rotation strategy: Selection of programs based on business scenarios:

Third, do not panic when encountering lag

When you find that the proxy response slows down, don't rush to change the IP first, try these three axes:

1. Try switching protocols in the client (HTTP/HTTPS back and forth)
2. Reduce the number of concurrencies from the current IP to half of the original number
3. Ping the gateway latency with the diagnostic tool provided by ipipgo

IV. QA time

Q: Is it worth buying a static proxy for $35 a month?
A: If you're in the business of cross-border e-commerce logging in that requires a fixed IP, it's definitely worth it. It costs more to keep your own server, not counting the risk of being blocked

Q: Where is Dynamic Agent Enterprise Edition expensive?
A: The main thing is that the IP pool is 5 times larger and supports filtering by ASN number. For example, if you want Deutsche Telekom's IP segment, the standard version may wait for half a day, but the enterprise version comes out in seconds!

Q: Why do you recommend the client over the API?
A: The client of ipipgo comes with intelligent routing, which will automatically select the best route when encountering connection problems. If you interface with the API yourself, you have to deal with all kinds of exceptions, which is time-consuming and laborious.

V. How can maintenance costs be saved?

Tell a real case: a cross-border e-commerce team with the standard version of the dynamic agent, monthly traffic costs more than 900. Later, it switched toStatic IP+Dynamic Proxy Combination SolutionThe core business uses static IP to ensure stability, and the crawler business uses dynamic proxies to go through the volume, and the cost is straight down to less than 500. Specific programs can find ipipgo customer service to do customization, their 1v1 program is free.

Lastly, I would like to remind you not to believe in those permanent free proxy services. Regular service providers like ipipgo, the price of 7.67 yuan / GB is already considered the floor price, the key is that people clearly marked prices do not engage in hidden pit. Maintenance agent this thing with the car like, regular maintenance of the money spent, always better than halfway broken down delay business is not strong?
