What does HTTP proxy mean: HTTP proxy principle

Hands-on dismantling of the HTTP proxy courier principle

Imagine you buy online to let the neighborhood post office to collect packages, HTTP proxy is the "courier collection point". When you type a URL into your browser, theThe request will first run to the proxy server and turn around., just like a courier arrives at the post station before being forwarded to you. In this process, the website sees the address of the post station (proxy IP), not the real address of your home (local IP).

A three-minute look at the workflow of proxy servers

Use the analogy of ordering from a breakfast place:
1. you (the client) say you want meat and soy milk (access request)
2. Attendants (proxy servers) note down requirements
3. Kitchen (target site) to prepare meals
4. the waiter brings your breakfast back to you

import requests

proxies = {
    'http': 'http://账号:密码@ipipgo proxies:port',
    'https': 'http://账号:密码@ipipgo proxy:port'
}
response = requests.get('destination URL', proxies=proxies)

These scenarios require an HTTP proxy

- e-commerce price comparison: When the same product is displayed at different prices in different regions, use a proxy IP to switch regions to view the real offer.
- Anti-blocking of accountsMulti-account operation, each account is bound to an independent proxy IP, to avoid the correlation of blocked numbers.
- data acquisition: When crawling public data, use ipipgo's dynamic IP pool rotation to prevent triggering the anti-climbing mechanism

Look for these three things when choosing a proxy service provider

1. IP purity: With self-hosted server rooms like ipipgo, IPs are not reused!
2. responsiveness: measured ipipgo node latency is basically within 50ms
3. Protocol Support: In addition to HTTP/S, support protocols such as SOCKS5

QA time: what you might want to ask

Q: Is it illegal to use an HTTP proxy?
A: It's perfectly legal! It's as normal as using a courier locker to collect your mail, but remember to follow the site's rules of use.

Q: What is the difference between free proxies and ipipgo paid proxies?
A: Free proxies are like public restrooms, anyone can use them and they are not hygienic. ipipgo's exclusive IP pool is like a private restroom, clean and safe.

Q: How can I tell if a proxy is in effect?
A: Visit the detection page provided by ipipgo official website, it will show the currently used proxy IP and geographic location.

Why recommend ipipgo

The difference between a homegrown chicken farm (engine room) and a vegetable market (public engine room):
- 24-hour technical customer service returns work orders in seconds
- Dynamic IP survival cycle 5-30 minutes for automatic replacement
- Support pay-as-you-go, use as much as you need
New users get a 1G traffic package with registration, which is measured to be enough to run half a month's worth of daily data collection tasks.

Lastly, I would like to remind you that choosing an agent is like looking for a partner, don't just look at the appearance (price), the key is to look at the inner (quality of service). Don't panic if you can't connect to the IP, ipipgo can get a new IP by refreshing the background with a single click, which is more convenient than changing socks.
