Proxy IP website principle: proxy website working principle and technical analysis

What the hell is a proxy IP anyway?

Let's start with an analogy, there is a courier cabinet in front of your neighborhood. Zhang San wants to send you something, but he does not want to send it directly to your door, put the courier into the cabinet. At this time, the courier cabinet is equivalent to the role of proxy IP-The delivery address that others see is the location of the delivery locker, not the actual door number of your homeThe

Properly speaking, a proxy IP is an intermediate server that sends and receives data on the Internet for you. When your request is forwarded through a proxy server, the target website sees the IP address of the proxy server, not the real address of your local machine. It's like wearing a mask to a party, others can only see the mask.

How does the proxy site work?

The whole process is divided into three key steps:

1. Your device sends the request to the proxy server (like handing a delivery to a courier locker)
2. Proxy server uses its own IP to fetch data from the target website (courier locker sends courier to pick up the goods)
3. The data returned by the target site goes to the proxy server first, and is then transferred back to you (the courier puts the package back in the locker and you pick it up yourself)

Here's an easy place to step in:Not all proxies can connect in the same way. There are three common types of protocols:

Doorways in technical realization

Give an example of actual code, using Python to access a website through a proxy:

import requests

 This should be replaced with the real proxies
proxies = {
    'http': 'http://user:password@ipipgo-proxy-server:port',
    'https': 'http://user:password@ipipgo-proxy-server:port'
}

response = requests.get('https://example.com', proxies=proxies)
print(response.text)

Notice the three key points in the code:

1. Write the protocol type correctly (http/https should not be confused)
2. The authentication information format isUsername:Password@Server Address:Port
3. The way it is configured can vary from one programming language to another

What are the points to look for when choosing an agency service?

Based on our real-world experience at ipipgo, the top three most common problems users encounter are:

1. IP pool is too small resulting in frequent blocking
2. Slow connections affect efficiency
3. Limited functionality due to incomplete protocol support

Here to put a real case comparison: a customer with ordinary agent to do data collection, every day was blocked 200 + times. Change to ipipgoDynamic Residential (Enterprise Edition)After the package, the blocking rate drops directly to less than 3 times per day. The secret is that our IP pool is updated daily with more than 20% resources to ensure IP freshness.

Frequently Asked Questions

Q: What should I do if my proxy IP is slow?
A: Priority check whether the protocol type matches, followed by switching to a geographically closer node. ipipgo's TK leased line has been optimized for transmission speed.

Q: How do I test if the agent is valid?
A: You can use this command for a quick test:
curl --proxy socks5://ip:port https://api.ipipgo.com/check
