Web Proxy Server: Proxy Server Types and Build Configuration Basic Tutorial

A proxy server in the end what is the use? Teach you to recognize the doorway

Friends engaged in the network understand that some operations are like dancing in shackles - such as bulk registration accounts are always blocked, crawling data by the site anti-climbing mechanism to intercept. At this time, we need a proxy server to act as a "stand-in actor", using other people's network identity to help us work. There are three common types of proxies on the market:

Residential AgentsMost like a real person surfing the web, with IP address from home broadband, for scenarios where you need to disguise a real user;Data Center AgentsFast response time thief, but easily recognized by websites;Exclusive AgentIt's the equivalent of a private, exclusive channel, and the stability can't be beat but it's also expensive.

Second, ride your own agent or buy a service? Old Driver's Experience

Tossed their own proxy server know, buy cloud servers, with the environment, maintenance of the IP pool of these things how bad. Take the most common Squid proxy build, just configure a basic version will have to toss half a day:

 Install the Squid service
sudo apt-get install squid

 Modify the configuration file
http_port 3128
visible_hostname my_proxy
acl localnet src 192.168.0.0/24
http_access allow localnet

And that's not even counting the IP blocking, changing servers, and dealing with CAPTCHA crap. Measured the cost of maintaining their own proxy pool, the monthly cost of the server alone will have to be four figures to start. So now smart people are directly looking for professional service providers, such asDynamic Residential Proxy for ipipgo, $7+ for 1 G of traffic is much more cost effective than keeping your own server.

III. Proxy IP anti-blocking practical skills (key notes)

Recently, while helping a friend tweak a crawler system, I realized that there is something to be said for using proxies:

• Don't use a fixed switching frequency, it's safer to switch IPs at random intervals of 0.5-3 seconds.
• Each IP is best to visit only 10-20 pages on the change, like shopping Taobao like natural browsing
• Remember to set the request header, especially the User-Agent to follow the IP address geolocation change

To cite a negative example: before using a free proxy pool, 20 consecutive requests with the U.S. IP, the result was the target site directly ban the entire IP segment. Later, I switched toStatic residential proxy for ipipgoThe company's TK dedicated line, the collection efficiency is directly doubled and not blocked.

IV. QA time: a guide for novices to avoid the pitfalls

Q: What should I do if I always say that the proxy IP is slow?
A: First look at the protocol to choose the right, do data collection priority with socks5 protocol. If you use ipipgo's service, remember that their cross-border line comes with acceleration, the actual download speed can reach 50Mbps+.

Q: How do I choose a package for my enterprise level needs?
A: average daily request volume of more than 50,000 times, directly on the dynamic residential (Enterprise Edition), support for concurrent number of automatic retry with request failure. An e-commerce friend changed this program, store management tools at the same time logging in 200 + accounts are not stuck!

V. Why recommend ipipgo? real experience report

I've used 7 or 8 agencies and finally settled on ipipgo for three main reasons:

1. He's got it.Residential IP with direct carrier signingIt's not like some service providers that pass off server room IPs as their own.
2. be in favor ofpay per volumeThe price of $7.67/G for a small team with a standard version of dynamic proxies is a good deal.
3. Fast technical response, the last time I encountered the IP can not be connected, customer service in 10 minutes to change the new batch!

A special shout-out to theirSERP APIDo search engine optimization counterparts should understand that the direct return of structured data to save how much parsing effort. Before the manual processing of 1000 search results to 2 hours, now call the interface 5 minutes to get.

Package Comparison Table (2024 latest version):

Dynamic residential (standard): for individual developers, $7.67/GB
Dynamic Residential (Business): with IP rotation guarantee, $9.47/GB
Static homes: A must for long term operation, $35/IP monthly rent

Say a real case: a cross-border e-commerce friends, with a static IP package to manage 50 store accounts, with ipipgo client set up whitelisting, half a year have not triggered the platform's wind control mechanism.

Six, white can understand the configuration tutorials

In the case of Python crawlers, it's super easy to extract proxies using the ipipgo API:

import requests

def get_proxy(): api_url =
    api_url = "https://api.ipipgo.com/get?type=s5"
    resp = requests.get(api_url).json()
    return f'socks5://{resp["ip"]}:{resp["port"]}'

 Example of use
proxy = get_proxy()
requests.get('https://目标网站.com', proxies={'http': proxy, 'https': proxy})

Note that to install the requests library, newbies are advised to use the client tool they provide directly, the graphical interface point and click the mouse to switch the geographic location. There is a friend who does overseas questionnaires, relying on this tool can be completed every day more than 30% of the amount of tasks.
