HTTP 444 Error: Nginx Timeout Solution

What's wrong with HTTP 444 errors?

Recently, many brothers with Nginx server ran to ask, encountered a strange 444 error, the page directly can not open without any prompt. To put it bluntly, this is the Nginx active disconnection of the tawdry operation, mainly because the server feels that the request time is too long do not want to serve. At this time, if you use a fixed IP to visit, it will be treated as a suspicious person to pull the black.

Why does a proxy IP cure this problem?

For example, if you go to the bank and are left hanging at the window for half an hour, you must have to change counters, right?Dynamic Proxy IP is this counter change operationipipgo's intelligent switching technology can make your request like the Monkey King's detachment, changing a new IP address every time you visit, so the server won't have time to determine whether you are a malicious request or not.

Hands on with ipipgo for 444

The first step is to go to the ipipgo website and get a package, they are recommended to use theirDynamic Residential Agents, this thing is more like a real person operation than a server room IP. After you get the API interface, change your request code according to this configuration:

 Python example (remember to replace your_api_key with your own)
import requests
proxy = {
    'http': 'http://user:your_api_key@gateway.ipipgo.com:8080',
    'https': 'http://user:your_api_key@gateway.ipipgo.com:8080'
}
response = requests.get('Your destination URL', proxies=proxy, timeout=15)

Here's the point! Remember to set the timeout to15 seconds or lessThe average response time of ipipgo's IP pool is only 3 seconds, so it is easy to trigger the server protection mechanism if you set it for too long.

Frequently Asked Questions First Aid Kit

Q: What should I do if I change the proxy IP or report 444?
A: 80% is IP switching is not fast enough, go to ipipgo console to put theAutomatic frequency switchingSet it to 30 seconds/time, don't worry about the traffic, stability is the most important thing.

Q: What if I need to open multiple crawler tasks at the same time?
A: Directly on ipipgo'sMulti-Threading PackageSupport 500 different IP channels at the same time, and remember that each thread is equipped with independent proxy parameters.

A guide to pitfall prevention (emphasis added)

Seen too many people fall on their asses here:
1. don't write dead IP addresses in the code, use ipipgo'sDynamic API Interfaceauto-acquisition
2. Don't fight with CAPTCHA, call ipipgo'sCaptcha Bypass Servicesave time and effort
3. 3-5am when the server is the loosest, that's when it's on.timed taskDouble the success rate

Finally nagging, with ipipgo remember to regularly go to the background to refresh the IP pool, their IP survival cycle is dynamically adjusted, happen to double eleven such a big promotion, in advance of the expansion of capacity quasi right. What do not understand directly to their technical support, the response speed faster than the delivery boy.
