Principles of Web Proxy: How Web Proxy Works in Detail

The real gun says agent: network agent in the end how to play?

Many friends have heard of proxy IP, but really want to practice on the confusion. Let's not organize the theory of those imaginary head of the brain, directly break open the crumbs to understand. To give a grounded example: you want to go to the market to buy food and do not want to be recognized by the vendors, find an errand boy to buy on behalf of the - this is the most straightforward analogy of proxy IP.

Proxy IP's three-pronged principle

The proxy server is like a relay station with a three-step workflow:

1. your device → proxy server (with new IP address)
2. Proxy server → target website
3. target website → proxy server → your device

Here's the point:Throughout the process, the target website sees only the IP of the proxy server, which is like going out with a mask on. Professional service providers like ipipgo keep thousands of masks in their IP pools, ready to be swapped out.

These are the scenarios you can definitely use

To give a real-life example: an e-commerce team using ipipgo'sDynamic Residential IP, successfully bypassing the platform wind control, than the efficiency of the price increased by three times. Their responsible person said, "Previously, seven or eight IPs were blocked every day, and now with dynamic rotation, it's like opening a stealth hang."

Hands-On: Python Docking Agent

Take the ipipgo API as an example, and complete the configuration in three steps:

import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

resp = requests.get('destination URL', proxies=proxies, timeout=10)
print(resp.text)

Be careful to replace it with your own account information, and don't set the timeout more than 10 seconds. If you get a 407 error, it's probablyWrong account password.Or the package has expired.

Guide to avoiding the pit: five minefields in choosing an agent

1. Free agents should be used with caution: nine out of ten free agents are pits, and the remaining one is digging a pit.
2. Pay attention to the level of anonymity: high anonymity proxies can hide the real IP address.
3. Protocols should be compatible: HTTP for web access and SOCKS5 for data transfer.
4. Don't settle for less: less than 2 seconds is enough!
5. After-sales guarantee to confirm: like ipipgo dare to promise15-minute fault responsereliable

Frequently Asked Questions

Q: Will the proxy IP be found by the website?
A: Use a high anonymity proxy + a regular service provider (like ipipgo) and you will basically not be recognized. But don't use those crappy shared IPs.

Q: How long does a proxy IP last?
A: Dynamic IP a few minutes to change, static IP can be used 1-30 days ranging. ipipgoLong-lasting static IPStability is good, we measured 21 days of continuous use without dropouts.

Q: What should I do if my agent is slow?
A: First ping test latency, more than 200ms suggest changing nodes. If you are an ipipgo user, their client comes with aIntelligent Route SwitchingFunction that automatically selects the fastest route.

Q: What is the appropriate number of IPs needed at the same time?
A: 10-50 is enough for small projects, 500+ is recommended for large business. ipipgo'sElastic IP PoolSupports expansion at any time, use as much as you need without waste.

Lastly, a word from the heart: don't just look at the price when choosing an agency service.IP qualityrespond in singingafter-sales serviceThat's the key. Like some small workshops sell cheap proxies, with either dropped or ban, but delayed the work. Our team has been using ipipgo for the past two years, mainly because of their IP survival rate and after-sales response speed, encountered problems with engineers directly remote assistance, this is really worry-free.
