HTTP Proxy: How Forward Proxying Works

First, what is the HTTP forward proxy? First nag to understand the basic concepts

We usually surf the Internet like receiving a courier, your device (mobile phone/computer) is the recipient, the web server is the shipper. HTTP forward proxy is an additionalCourier collection point--Proxy servers. When you use ipipgo's proxy service, the access request takes a detour to their servers before being forwarded to the target site.

Let's take a real example: you ask your secretary to help you order takeout, and the secretary is the agent. The restaurant sees the secretary's cell phone number (proxy IP), but does not know your real number (real IP). This not only protects your privacy, but also avoids limiting the number of visits to certain websites.

Two, how does this thing work? I'll draw you a flow chart.

Normal Internet flow:
Your computer → Direct connection to the web server

After using a positive proxy:
Your computer → ipipgo proxy server → web server

 Example of Python using a proxy (remember to replace the address with ipipgo)
import requests

proxies = {
    'http': 'http://user:password@proxy.ipipgo.com:8080',
    'https': 'http://user:password@proxy.ipipgo.com:8080'
}

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

Why use proxy IP, these scenarios are particularly practical

Fourth, hand to teach you to configure the agent

Focused attention:The proxy information obtained in the ipipgo backend contains three key parameters:

1. Server address (e.g. proxy.ipipgo.com)
2. Port number (commonly 8080, 8888)
3. Account password (some packages require verification)

Browser setup steps (using Chrome as an example):

1. Open Settings → Advanced → System → Open Proxy Settings
2. Fill in the manual proxy configuration with the address provided by ipipgo.
3. Remember to test the connection after saving

V. Frequently Asked Questions for Beginners QA

Q: What should I do if the proxy IP suddenly doesn't work?
A: First check whether the network is normal, and then confirm whether the proxy information is out of date. ipipgo's proxy packages come with 24-hour customer service, so if you encounter any problems, you can directly find their technical staff.

Q: Why does the Internet speed slow down after using the proxy?
A: Maybe the node load is high, in ipipgo background switch other regional nodes to try. The quality of their BGP lines is good, usually the delay can be controlled within 200ms.

Q: Can one agent be used for multiple devices at the same time?
A: Depending on the type of package bought, ipipgo's enterprise version supports multi-terminal sharing, and the personal version suggests single-device use.

VI. What are the doors to look for when choosing an agency service?

Agency services are a mixed bag on the market and it is recommended to focus on these three points:

• IP Survival Time: ipipgo's dynamic proxies automatically change IPs every 5 minutes.
• Geographic location coverage: their home support 200 + city node switching
• Protocol support: in addition to HTTP/HTTPS, also supports SOCKS5 protocols

Lastly, I would like to say: proxy IP is like a "cloak of invisibility" in the network world, which is twice as effective with half the effort. But remember to comply with the use of the rules of each platform, ipipgo's legal compliance proxy pool in this regard, the control is quite strict, suitable for long-term stable use.
