Modifying User-Agent: UA Modification Configuration Steps and Tips

I. What is UA? Why change it?

To use an analogy, User-Agent is like your web ID. Every time you visit a website, your browser automatically tells the person, "I'm Chrome version 120, visiting from a Windows computer." Some websites restrict access based on this information, such as blocking crawlers.

Assuming that you are accessing from the U.S. proxy, the UA displays the Chinese system time, and the website can immediately recognize it. Last year, an e-commerce friend, with a static IP collection of data is always blocked, and later found that the UA with the characteristics of the python code, changed to the browser UA directly doubled the success rate.

Here's the point:When using ipipgo's proxy service, you must disguise the UA as a real browser in order to maximize the effect of the proxy. Especially with their cross-border dedicated packages, with the right UA settings, the access stability improvement is super obvious.

Second, the hand to teach you to change UA

Here are two of the most practical methods recommended, the white man can also easily get started:

Method 1: Direct code change (Python example)

import requests

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"
}

 Recommended for use with ipipgo's proxies
proxies = {
    "http": "http://用户名:密码@gateway.ipipgo.com:9020",
    "https": "http://用户名:密码@gateway.ipipgo.com:9020"
}

response = requests.get("https://目标网站", headers=headers, proxies=proxies)

Method 2: Browser plug-in modification

Install a User-Agent Switcher plugin (Chrome/Firefox have), a key to switch the UA of different devices. test with ipipgo's TK line, switch to TikTokAPP's UA access, the data collection success rate can be 92% or more.

Third, the golden combination of agent + UA play

Changing the UA alone is not enough, it has to be used with a proxy. Here is a useful configuration table:

For example, to do cross-border e-commerce friends, with ipipgo's static residential agent, each store account binding fixed UA + fixed IP, safe operation for 2 years without problems.

IV. Guidelines for avoiding pitfalls (blood and tears experience)

1. Never use a fake UA.: Some tools generate incorrectly formatted UA's, such as writing the Chrome version as 150.0 (when it's actually only 120 at the latest), and this kind of low-level error is the easiest to recognize

2. Note the time stampSome websites will check the system time in the UA, if you use a US IP but display Beijing time, you will be exposed immediately. It is recommended to use the time zone synchronization function that comes with the ipipgo client.

3. Mobile UA with device IDFor Android, the UA must contain an identifier such as Build/MRA58N, and for Apple devices, a specific model number such as iPhone 13,4.

V. Frequently Asked Questions QA

Q: What should I do if I am still recognized after changing my UA?
A: Suggest three steps to troubleshooting: 1. check whether the proxy is in effect (test with ipipgo client) 2. confirm that the UA format is correct 3. clear the browser cache or change to no trace mode

Q: How often should I change my UA?
A: According to the business intensity of the decision: ordinary collection of 1 hour to change once, high-concurrency business is recommended with dynamic residential agent, each request with a new UA

Q: Which ipipgo package works best with UA mods?
A: Ordinary users choose dynamic residential (standard) enough to use, need to fix the identity of the business (such as social accounts) with static residential, enterprise-class data collection directly to find them customized solutions

VI. Sharing of special techniques

Recently, I found out a tiresome operation: when using ipipgo's API to extract proxies, you can directly specify the UA characteristics in the request parameters, and their system will automatically match the UA of the real devices in the same region. e.g. like this:

https://api.ipipgo.com/get?key=你的密钥&ua=chrome_mac

So that the proxy IP, UA characteristics and geographic location of the exact match, pro-tested anti-climbing strict e-commerce platform, continuous collection for 3 days did not trigger verification.

Lastly, I would like to remind you that ipipgo's first order for new users has a hidden offer (not written on the official website), and before placing an order, you can get a 10% discount by looking for customer service and reporting the secret code "UA2024″. This was revealed last week when their director of operations live broadcast, it is estimated that after a period of time will be canceled, and use and cherish.
