How do http and reverse proxy work? Difference between forward proxy and reverse proxy application scenarios

Hands-on teaching you to play HTTP proxy and reverse proxy

A lot of friends who just contacted the network proxy, often confused about the difference between forward proxy and reverse proxy. Today, we will use the vernacular to make it clear, especially in conjunction with ipipgo's proxy service, to teach you how to use these techniques in the actual project.

First, the correct way to open the HTTP proxy

Take a real example: Xiao Wang do cross-border e-commerce need to log in 10 store accounts at the same time, directly with their own network login will be detected by the platform associated. At this time, it is necessary to useDynamic Residential Agents, change different IPs for each request.

import requests

proxies = {
    'http': 'http://用户名:密码@proxy.ipipgo.com:24000',
    'https': 'http://用户名:密码@proxy.ipipgo.com:24000'
}

response = requests.get('https://目标网站.com', proxies=proxies)

Be careful when using ipipgo's dynamic proxy:

1. Session mode selection: Rotating IPs are good for bulk registrations, and sticky sessions are good for operations that need to keep you logged in.
2. Positioning settings: When doing localized operations, it is recommended to specify state/city level positioning
3. Protocol selection: Use HTTPS if the site has images to load, use HTTP for plain text data to save more traffic

Second, the reverse proxy of the practical use of the wonderful

Doing overseas live broadcast Lao Zhang encountered a problem: the audience is distributed in five continents, the live broadcast lag is serious. Use ipipgo'sTikTok SolutionsAfter building a reverse proxy cluster, traffic is automatically distributed to the nearest node.

Reverse proxy configuration example (Nginx):

server {
    listen 80; server_name yourdomain.com; server_name yourdomain.com
    server_name yourdomain.com;

    server { listen 80; server_name yourdomain.com; location / {
        proxy_pass http://ipipgo-tiktok-node; proxy_set_header
        proxy_set_header X-Real-IP $remote_addr; }
    }
}

There are three major benefits to this architecture:
1. Hiding real server IP, anti-DDoS attacks
2. Automatic load balancing, New York users go to the U.S. East node
3. Caching of static resources to reduce server pressure

III. Guidelines for selecting forward and reverse proxies

IV. Frequently Asked Questions QA

Q: How do I choose between dynamic and static proxies?
A: the need for long-term maintenance of the session (such as store backstage) with static, short-term operation (price comparison, crawler) with dynamic

Q: What should I do if my proxy IP is always blocked?
A: three suggestions: 1) use ipipgo's real residential IP 2) set a reasonable request frequency 3) with User-Agent randomized

Q: Which program is recommended for cross-border e-commerce?
A：Order processing with a static agent to ensure stability, the collection of goods with a dynamic agent to prevent blocking, logistics inquiries to go to the international special line!

V. Guidelines for avoiding pitfalls

Recently, I've helped a client deal with a typical case: a company used an ordinary server room agent to do social media operations, resulting in the total loss of 200 numbers. Change to ipipgo'sStatic Residential AgentsAfter that, the survival rate increased to 92%. here's a tip: when doing account matrix, different business lines should use IP segments in different cities.

Lastly, a reminder: selecting an agency service depends onIP purityrespond in singingProtocol Support. Like ipipgo this support SOCKS5 protocol, in the processing of video streaming data speed can be faster 30% or so. Specifically how to configure their technical customer service to find a case library, than their own blindly figure out how to save a lot of trouble.
