HTTP Proxy Meaning: Forward Proxy Principles Explained

What the heck is an HTTP proxy?

To put it bluntly, an HTTP proxy is like a courier boy who runs errands for you when you shop online. When you want to visit a website, not directly to knock on the door, but let this intermediary to help you get the data. For example, you use the browser to visit Taobao, this time if you hang a proxy, the actual proxy server for you to deal with Taobao server.

Here's a key point many people get confused about:The forward proxy is actively configured by the client. It's like filling in the address of a courier station in your phone settings and telling your phone that all future packages will be routed through that station. Unlike reverse proxies, forward proxies leave the decision entirely in the hands of the user.

How do you play forward proxying with proxy IPs?

In practice, the proxy IP is the work license of the courier. When you get a proxy IP in ipipgo, it is equivalent to getting a "pass" for a specific region/carrier. For example, configure a Python request like this:

import requests

proxies = {
    'http': 'http://user:pass@proxy.ipipgo.cc:9020',
    'https': 'http://user:pass@proxy.ipipgo.cc:9020'
}

response = requests.get('http://example.com', proxies=proxies)

Notice in the code theuser:pass@In part, this is the account password for the proxy service. ipipgo's proxies all use this authentication method, which is much safer than those free proxies - after all, who doesn't want their delivery to be switched halfway through the day, right?
